Modify the given program to use a loop to output an arrow head of width arrow_head_width.
Answers
Answer:
Here is the C program:
#include <stdio.h> //to use input output functions
int main(void) { //start of main function
int arrowBaseHeight = 0; //stores value for arrow base height
int arrowBaseWidth = 0; //stores value for arrow base width
int arrowHeadWidth = 0 ; //stores value for arrow head width
int i, j; //to traverse through the rows and columns
printf("Enter arrow base height:\n"); //prompts user to enter arrow base height value
scanf("%d", &arrowBaseHeight); //reads input value of arrow base height
printf("Enter arrow base width:\n"); //prompts user to enter arrow base width value
scanf("%d", &arrowBaseWidth); //reads input value of arrow base width
while (arrowHeadWidth <= arrowBaseWidth) { //iterates as long as the value of arrowHeadWidth is less than or equals to the value of arrowBaseWidth
printf("Enter arrow head width:\n"); //prompts user to enter arrow head width value
scanf("%d", &arrowHeadWidth); //reads input value of arrow head width
printf("\n"); }
for (i = 0; i < arrowBaseHeight; i++) { //iterates through rows
for (j = 0; j < arrowBaseWidth; j++) { //iterates through columns
printf("*"); } //prints asterisks
printf("\n"); } //prints a new line
for (i = arrowHeadWidth; i > 0; i--) { //loop for input length
for (j = i; j > 0; j--) { //iterates for triangle ( to make arrow head)
printf("*"); } //prints asterisks
printf("\n"); } } //prints new line
Explanation:
The program asks to enter the height of the arrow base, width of the arrow base and the width of arrow head. When asking to enter the width of the arrow head, a condition is checked that the arrow head width arrowHeadWidth should be less than or equal to width of arrow base arrowBaseWidth. The while loop keeps iterating until the user enters the arrow head width larger than the value of arrow base width.
The loop is used to output an arrow base of height arrowBaseHeight.
The nested loop is being used which as a whole outputs an arrow base of width arrowBaseWidth. The inner loop draws the stars and forms the base width of the arrow, and the outer loop iterates a number of times equal to the height of the arrow.
The last nested loop is used to output an arrow head of width arrowHeadWidth. The inner loop forms the arrow head and prints the stars needed to form an arrow head.
The screenshot of output is attached.

Explanation:
The algorithm S(A, n, i) selects all the j-th smallest elements (with j ≤ i) from an array A of n elements, by using linearselect to select each of the j-th smallest elements (with j ≤ i). Clearly, one could also implement S alternatively as T(A, n, i), which first sort A (on average-case and on worstcase, the sorting takes time O(n log n) using mergesort) and then select the first i elements. Please compare the average-case complexities of the two algorithms; i.e., For the average-case complexities, under what conditions (on the choices for i), S is better than T or vice versa
Answers
Answer:
Follows are the solution to this question:
Explanation:
In the linear selected algorithms scans the given field sequentially but instead calculates the fixed amount by crossing the items throughout the list since they are displayed. Take into consideration the various chosen algorithm:
S(A, n, i) Algorithm:
In array B, copy array A items.
To save results, construct an array C of height.
Start Loop j = 0 to i-1.
Determine array B's lowest value.
In array C, also save the minimum value.
Delete from array B the minimum value.
Back the C array.
Analysis of runtime:
In i iterations, the external loop is used, although i have to compute the number of small lots.
This internal loop should run and calculate the minimum variable, whereby n is the input array length at the most values of n.
Its cumulative runtime is equal to O(in)+C =
O(in). All remaining operations are done at a precise rate.
The combine type technique requires that division concept to
sort the sorted array either in or upwards backward order.
Follow the appropriate method using merge type to
select the shortest items of a certain list.
T (A, n, i) algorithm:
In B array, copy array A elements.
To save the output, build a C array of sizes.
Using merge form in an increasing order to sort all items of the B list.
Start the loop j= 0 to i-1.
Save A[j] value in C[j].
Return array C,
return array C.
Analysis of run time:
The combined function requires O (n log n) to arrange a size n list.
Its number of samples in the process to construct the resulting sequence becomes equal to i since i is the minimum number of elements to also be calculated. All remaining transaction is performed in continuous time.
The time to work is O (n log n) + O i + C = O (n log n). The time needed.
The complexities of the following algorithms are similar:
Scenario 1: S is stronger than to the T-algorithm
Consider the number for smallest elements to also be calculated or even the I value is significantly smaller than the number of array elements. Let i = 2 and n = 16.
Its algorithm S requires O(in) time for both the calculation of a result, who in this case is equivalent to (2 16).
If algorithm T finds the initiative of O (n log n), who in this case is equivalent to (16 logs 16) = (16 4).
The S method, therefore, operates better than that of the T algorithm, if another I value exceeds the log n value.
Scenario 2: Algorithm T is much more successful that algorithm S
Evaluate if the number of components which must be calculated is smaller or if the value of I is comparable with that of the items inside the array.
Let the I = 12 quality and n = 16 value. Its S method applies O(in) time, and in this, the situation is just like (12 16).
Hence, the algorithm T performs better than the algorithm S when the value of i is greater than the value of the log n.
Write a Python program that verifies the formula with the help of the Python Math module. Note that the trigonometric functions in the module act on the angles in radians. Your program should perform the following steps 3 times:_____.
1. Pick a random number between 0 and 180 degrees representing an angle in degrees, say Dangle
2. Convert the angle from degrees to radians, say Rangle
3. Use the Math module to find and print the values of sin(Rangle) and cos(Rangle), and
4. Compute and print the value of the above expression: sin^2(Rangle) + cos^2(Rangle).
You can then visually verify if the result printed is 1 (or close to it).
Hint: angle_in_radians = (angle_in_degrees * Pi)/180
Answers
Answer:
Written in Python
import math
import random
Dangle = random.randint(0,181)
pi = 22/7
Rangle = Dangle * pi/180
Rsin = math.sin(Rangle)
Rcos = math.cos(Rangle)
Result = Rsin**2 + Rcos**2
print("Result = "+str(Result))
Explanation:
The next two lines import math and random library respectively
import math
import random
This line generates a random integer between 0 and 180
Dangle = random.randint(0,181)
This line initializes pi to 22/7
pi = 22/7
This line converts angle to radians
Rangle = Dangle * pi/180
The next two lines calculate the sin and cosine of the angle in radians
Rsin = math.sin(Rangle)
Rcos = math.cos(Rangle)
This line implements sin^2 theta + cos^2 theta
Result = Rsin**2 + Rcos**2
This line prints the required Result
print("Result = "+str(Result))

Summary: Given integer values for red, green, and blue, subtract the gray from each value.
Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).
Given values for red, green, and blue, remove the gray part.
Ex: If the input is:
130 50 130
the output is:
80 0 80
Find the smallest value, and then subtract it from all three values, thus removing the gray

The following iteration checks for the smallest for red, green, blue
if(red <= blue && red <= green){
smallest = red;
}
else if(green <= red && green <= blue){
smallest = green;
}
else{
smallest = blue;

Ex: If the input is 20.0 3.1599, the output is: 1.57995 7.89975 63.198 Note: Small expression differences can yield small floating-point output differences due to computer rounding. Ex: (a + b)/3.0 is the same as a/3.0 + b/3.0 but output may differ slightly. Because our system tests programs by comparing output, please obey the following when writing your expression for this problem. First use the dollars/gallon and miles/gallon values to calculate the dollars/mile. Then use the dollars/mile value to determine the cost per 10, 50, and 400 miles. Note: Real per-mile cost would also include maintenance and depreciation.
Answers
Answer:
The Following are the code to this question:
def cost(miles, milesPerGallon, dollarsPerGallon):##defining a method cost that accepts three parameter
return miles / milesPerGallon * dollarsPerGallon# calculate cost and return it value
milesPerGallon = float(input('Enter miles/Gallon value: '))#defining variable milesPerGallon for user input
dollarsPerGallon = float(input('Enter dollars/ Gallon value: '))#defining variable dollarsPerGallon for user input
print('{:.5f}'.format(cost(10, milesPerGallon, dollarsPerGallon)))#call method and print its value
print('{:.5f}'.format(cost(50, milesPerGallon, dollarsPerGallon)))#call method and print its value
print('{:.3f}'.format(cost(400, milesPerGallon, dollarsPerGallon)))#call method and print its value
Output:
Enter miles/Gallon value: 20.0
Enter dollars/ Gallon value: 3.1599
1.57995
7.89975
63.198
Explanation:
In the above-given code, a method "cost" is defined, that accepts three value "miles, milesPerGallon, and dollarsPerGallon" in its parameter, and use the return keyword for calculating and return its value.
In the next step, two variable "milesPerGallon, and dollarsPerGallon" is declared, that use the input method with float keyword for input floating-point value.
After input value, it uses a print method with different miles values, which are "10,50, and 400", and input value to pass in cost method to call and print its return value.

A final conclusion paragraph will address my personal subjective opinion as to whether these technologies, in an overall sense are a benefit or hindrance to law enforcement efforts.

From utilizing computers in cars so officers could run a license plate and social security number to see if there are any warrants out for the person they stopped, to more advances such as carrying cell phones, GPS tracking systems in cars, crime mapping tools, information sharing between state and local law enforcement, to even sharing information across countries. Technology has come a long way in helping officers and other agents within the criminal justice system do their job.
Just a bit more about the advantages of the things mentioned above and time to move on. The most interesting thing is Geographic Information Systems (GIS), which has become a most important tool for law enforcement agencies. GIS, other mapping software and desktop computers now are capable of mapping and data analysis that is way above and beyond what used to be possible with backroom mainframe computers (Rubley, 2011).
Another great advancement is the widespread use of everyone using mobile devices. Many officers now use two to three cell phones.
Write some code that assigns True to the variable is_a_member if the value assigned to member_id can be found in the current_members list. Otherwise, assign False to is_a_member. In your code, use only the variables current_members, member_id, and is_a_member.
Answers
Answer:

member_id = 7
if member_id in current_members:
is_a_member = True
else:
is_a_member = False
print(is_a_member)
Explanation:
Although it is not required I initialized the current_members list and member_id so that you may check your code.
After initializing those, check if member_id is in the current_members or not using "if else" structure and "in" ("in" allows us to check if a variable is in a list or not). If member_id is in current_members, set the is_a_member as True. Otherwise, set the is_a_member as False.
Print the is_a_member to see the result
In the example above, since 7 is in the list, the is_a_member will be True

The program will then print out the total number and percentages of heads and tails. Use the increment operator to increment the number of tosses as each toss is input. For example, a possible sample dialog might be: For each coin toss enter either ‘h’ for heads or ‘t’ for tails. First toss: h Second toss: t Third toss: t Fourth toss: h Fifth toss: t Sixth toss: h Seventh toss: t Eighth toss: t Number of heads: 3 Number of tails: 5 Percent heads: 37.5 Percent tails: 62.5

tail = tail + 1
The next two lines print the number of heads and tails respectively
print("Number of head: "+str(head))
print("Number of tail: "+str(tail))
The next two lines print the percentage of heads and tails respectively
print("Percent head: "+str(head * 100/8))

Answer:
hope this helps...
Explanation:
A computer can only make a decision if it has been instructed to do so. In some advanced computer systems, there are computers that have written the instructions themselves, based on other instructions, but unless there is a “decision point”, the computer will not act on its own volition.

Easter Sunday is the first Sunday after the first full moon of spring. To compute the date, you can use this algorithm, invented by the mathematician Carl Friedrich Gauss in 1800:
1. Let y be the year (such as 1800 or 2001).
2. Divide y by 19 and call the remainder a. Ignore the quotient.
3. Divide y by 100 to get a quotient b and a remainder c.
4. Divide b by 4 to get a quotient d and a remainder e.
5. Divide 8 * b 13 by 25 to get a quotient g. Ignore the remainder.
6. Divide 19 * a b - d - g 15 by 30 to get a remainder h. Ignore the quotient.
7. Divide c by 4 to get a quotient j and a remainder k.
8. Divide a 11 * h by 319 to get a quotient m. Ignore the remainder.
9. Divide 2 * e 2 * j - k - h m 32 by 7 to get a remainder r. Ignore the quotient.
10. Divide h - m r 90 by 25 to get a quotient n. Ignore the remainder.
11. Divide h - m r n 19 by 32 to get a remainder p. Ignore the quotient.
Then Easter falls on day p of month n. For example, if y is 2001:
a = 6 h = 18 n = 4
b = 20, c = 1 j = 0, k = 1 p = 15
d = 5, e = 0 m = 0
g = 6 r = 6
Therefore, in 2001, Easter Sunday fell on April 15. Write a program that prompts the user for a year and prints out the month and day of Easter Sunday.
Part 1: Problem-Solving Phase
Using the Design Recipe, write each of the following for this problem:
Contract
Purpose Statement
Examples, making sure to include counter-examples
Algorithm (based on the above algorithm, completed with input/output steps)
Make sure to test your algorithm by hand with the examples to verify it before continuing to Part 2.
Part 2: Implementation Phase
Using Eclipse, write the Java program for the algorithm formulated in Part 1, and test your program with the examples from Part 1.
Make sure to incorporate your Contract, Purpose Statement and Examples as one or more comment blocks, and your Algorithm as line comments in your Java source code.

The program written in Java without comment is as follows
import java.util.*;
public class MyClass {
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
System.out.print("Year: ");
int y = input.nextInt();
int a = y%19;
System.out.println("a = "+a);
int b = y / 100;
System.out.println("b = "+b);
int c = y%100;
System.out.println("c = "+c);
int d = b / 4;
System.out.println("d = "+d);
int e = b%4;
System.out.println("e = "+e);
int g = (8 * b + 13)/25;
System.out.println("g = "+g);
int h = (19 * a + b - d - g + 15)%30;
System.out.println("h = "+h);
int j = c/4;
System.out.println("j = "+j);
int k = c%4;
System.out.println("k = "+k);
int m = (a + 11 * h)/319;
System.out.println("m = "+m);
int r = (2 * e + 2 * j - k - h + m + 32)%7;
System.out.println("r = "+r);
int n = (h - m + r + 90)/25;
System.out.println("n = "+n);
int p = (h - m + r + n + 19)%32;
System.out.println("p = "+p);
}
}
