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
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.

Explanation:
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.

Abstract
The purpose of this paper is to summarize the advantages of computers/software and the use of computer technology in investigations. Summarize the disadvantages to law enforcement with respect to the advancements of computers. Real cases will be researched in order to understand how computers can be utilized in criminal activities, as well as a case that the use of a computer was beneficial to the prosecution in a criminal case. 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.

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

red =input.nextInt();
green =input.nextInt();
blue =input.nextInt();
if(red <= blue && red <= green){
smallest = red;
}
else if(green <= red && green <= blue){
smallest = green;
}
else{
smallest = blue;
}
System.out.print((red - smallest)+" "+(green - smallest)+" "+(blue - smallest));
}
}
Explanation:
This line declares necessary variables
int red,blue,green,smallest;
This line prompts user for input of 3 numbers
System.out.print("Enter three numbers between 0 and 255 (inclusive): ");
The next three lines gets user inputs
red =input.nextInt();
green =input.nextInt();
blue =input.nextInt();
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;
}
This line prints the required output
System.out.print((red - smallest)+" "+(green - smallest)+" "+(blue - smallest));

Explanation:
This program outputs a downwards facing arrow composed of a rectangle and a right triangle. The arrow dimensions are defined by user specified arrow base height, arrow base width, and arrow head width. #include int main(void) {int arrowBaseHeight = 0;int arrowBaseWidth = 0;int arrowHeadWidth = 0;printf("Enter arrow base height:\n");scanf("%d", &arrowBaseHeight);printf("Enter arrow base width:\n");scanf("%d", &arrowBaseWidth);printf("Enter arrow head width:\n");scanf("%d", &arrowHeadWidth);printf("\n");// Draw arrow base (height = 3, width = 2)printf( "**\n");printf( "**\n");printf( "**\n");// Draw arrow head (width = 4)printf( "****\n");printf( "***\n");printf( "**\n");printf( "*\n");return 0;}a. Modify the given program to use a loop to output an arrow base of height arrow_base_height. b. Modify the given program to use a loop to output an arrow base of width arrow_base_width.c. Modify the given program to use a loop to output an arrow head of width arrow_head_width.
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.
