Consider the following code segment. int[][] arr = {{3, 2, 1}, {4, 3, 5}}; for (int row = 0; row < arr.length; row++) { for (int col = 0; col < arr[row].length; col++) { if (col > 0) { if (arr[row][col] >= arr[row][col - 1]) { System.out.println("Condition one"); } } if (arr[row][col] % 2 == 0) { System.out.println("Condition two"); } } } As a result of executing the code segment, how many times are "Condition one" and "Condition two" printed?
Answer:
Condition one - 1 time
Condition two - 2 times
Explanation:
Given
The above code segment
Required
Determine the number of times each print statement is executed
For condition one:
The if condition required to print the statement is: if (arr[row][col] >= arr[row][col - 1])
For the given data array, this condition is true only once, when
[tex]row = 1[/tex] and [tex]col = 2[/tex]
i.e.
if(arr[row][col] >= arr[row][col - 1])
=> arr[1][2] >= arr[1][2 - 1]
=> arr[1][2] >= arr[1][1]
=> 5 >= 3 ---- True
The statement is false for other elements of the array
Hence, Condition one is printed once
For condition two:
The if condition required to print the statement is: if (arr[row][col] % 2 == 0)
The condition checks if the array element is divisible by 2.
For the given data array, this condition is true only two times, when
[tex]row = 0[/tex] and [tex]col = 1[/tex]
[tex]row = 1[/tex] and [tex]col = 0[/tex]
i.e.
if (arr[row][col] % 2 == 0)
When [tex]row = 0[/tex] and [tex]col = 1[/tex]
=>arr[0][1] % 2 == 0
=>2 % 2 == 0 --- True
When [tex]row = 1[/tex] and [tex]col = 0[/tex]
=>arr[1][0] % 2 == 0
=> 4 % 2 == 0 --- True
The statement is false for other elements of the array
Hence, Condition two is printed twice

Build a dictionary whose keys are the lowercase letters, and whose values are sets of words which begin with that key letter. After processing the data, print the dictionary to the screen in alphabetical order aligned in two fixed sized columns. Such as:
Answer:
Follows are the code to this question:
def dic_sorted(data):#defining a method print_dic_sorted
s = data.split()#defining a variable that use split method
d = {} #defining a dictionary
alpha = '0123456789abcdefghijklmnopqrstuvwxyz' #defining a variable alpha that hold english alphabets values
for k in alpha:#defining for loop that stores values in the dictionary
d[k]= set()# use dictionary to set value in list
for i in s:# defining for loop to convert value in lower case
i = i.lower() #convert value into lower case by using lower method
a = i[0]# adding value into dictionary
d[a].add(i) # use add method to hold value in dictionary
for k,v in sorted(d.items()):#use for loop to convert value in assending order
if len(d[k])!=0: #use if block to check length of dictionary
print(k,":", sorted(v))#use print to sort value
f_name = 'input.txt'#defining a variable that open file
with open(f_name) as fi:#use open method to read file
data = fi.read() # read file data
dic_sorted(data)#calling method
output:
please find the attached file.
Explanation:
In the code, the "dic_sorted" method is used, which accepts a data variable as a parameter, and inside the method, a split method and an empty dictionary are defined, that converts and holds the value by alphabetical order, for this it defines three for loops.
In the first for loop, it holds a value in the dictionary, and in the second loop it converts a value into the lower case, and in the third loop, it stores the value in its alphabetical order.

differentiate between computer and computer system
A computer is a programmable device that can automatically perform a sequence of calculations or other operations on data once programmed for the task. It can store, retrieve, and process data according to internal instructions. A computer may be either digital, analog, or hybrid, although most in operation today are digital. Digital computers express variables as numbers, usually in the binary system. They are used for general purposes, whereas analog computers are built for specific tasks, typically scientific or technical. The term "computer" is usually synonymous with digital computer, and computers for business are exclusively digital.
The core, computing part of a computer is its central processing unit ( CPU), or processor. ... A computer system, therefore, is a computer combined with peripheral equipment and software so that it can perform desired functions.

Consider the following incomplete method, which is intended to return the longest string in the string array words. Assume that the array contains at least one element.
public static String longestWord(String[] words)
{
/* missing declaration and initialization */
for (int k = 1; k < words.length; k++)
{
if (words[k].length() > longest.length())
{
longest = words[k];
}
}
return longest;
}
Which of the following can replace /* missing declaration and initialization */ so that the method will work as intended?
a. int longest = 0;
b. int longest = words[0].length();
c. String longest = "";
d. String longest = words[0];
e. String longest = words[1];
Answer:
String longest = "";
Explanation:
The initialization that would allow the method to work as intended would be the following
String longest = "";
This is because the method is looping through the array provided as an argument and comparing each word in the array with the word saved inside the variable called longest. The length of both are compared and if the word in the array is longer than the string saved in the variable longest then it is overwritten with the word in the array.

Assume hosts A and B are each connected to a switch Svia 100-Mbps links. The propagation delay on each link is 25μs. The switch Sis a store-and-forward device and it requires a delay of 35μs to process a packet after is has received the last bit in the packet. Calculate the total time required to transmit 40,000 bits from Ato B in the following scenarios. (The total time is measured from the start of the transmission of the first bit at A, until the last bit is received at B. We always assume that links are bi-directional with the same transmission rate and propagation delay in each direction unless specifically instructed otherwise.)
Answer:
885 μs
Explanation:
Given that:
Switch via = 100 Mbps links
The propagation delay for each link = 25μs.
Retransmitting a received packet = 35μs
To determine:
The total time required to transmit 40,000 bits from A to B.
Considering the fact as a single packet:
Transmit Delay / link = size/bandwith
= 4×10⁴ bits / 100 × 10⁶ bits/sec
= 400 μs
The total transmission time = ( 2 × 400 + 2 × 25 + 35) μs
= (800 + 50 + 35) μs
= 885 μs

1.21 LAB: Divide by x
Write a program using integers user_num and x as input, and output user_num divided by x three times.
Answer:
Explanation:
The following code is written in Python. It is a function called divide_by_x and takes the user inputs as described. It then raises x to the third power and divides user_num by that number. This gives the same result as user_num divided by x three times. The answer is saved in the variable answer which is then returned to the user.
def divide_by_x(user_num, x):
answer = user_num / (x**3)
return answer
The program is an illustration of the division arithmetic operation.
The program in Python, where comments are used to explain each line is as follows:
#This gets input for user_num
user_num = int(input())
#This gets input for x
x = int(input())
This loop is repeated three times
for i in range(1,4):
#This divides user_num by x, each time
user_num /= x
#This prints the required output
print(user_num)
At the end of the program, user_num is divided three times by x and then printed.

Consider a disk that rotates at 3600 rpm. The seek time to move the head between adjacent tracks is 2 ms. There are 32 sectors per track, which are stored in linear order from sector 0 through sector 31. The head sees the sectors in ascending order. Assume the read/write head is positioned at the start of sector 1 on track 8. There is a main memory buffer large enough to hold an entire track. Data is transferred between disk locations by reading from the source track into the main memory buffer and then writing the data from the buffer to the target track. a. How long will it take to transfer sector 1 on track 8 to sector 1 on track 9
Answer:
19.71 ms
Explanation:
The disk rotates at 3600 rpm, hence the time for one revolution = 60 / 3600 rpm = 16.67 ms.
Hence time to read or write on a sector = time for one revolution / number of sectors per track = 16.67 ms / 32 sectors = 0.52 ms
Head movement time from track 8 to track 9 = seek time = 2 ms
rotation time to head up sector 1 on track 8 to sector 1 on track 9 = 16.67 * 31/32 = 16.15 ms
The total time = sector read time +head movement time + rotational delay + sector write time = 0.52 ms + 2 ms + 16.15 ms + 0.52 ms = 19.19 ms
It will take 19.19 ms to transfer sector 1 on track 8 to sector 1 on track 9
The given parameters are:
[tex]d_r = 3600 rpm[/tex] --- the disk rotation
[tex]s=32[/tex] --- the sectors in a track
Calculate the time (t) to complete one revolution
[tex]t = \frac{60}{d_r}[/tex]
[tex]t = \frac{60}{3600}[/tex]
[tex]t = \frac{1}{6}[/tex]
So, the time to read/write to a sector is:
[tex]T = \frac{t}{s}[/tex]
This gives
[tex]T = \frac{1/6}{32}[/tex]
[tex]T = \frac{1}{192}[/tex]
Convert to ms
[tex]T = \frac{100}{192}[/tex]
[tex]T = 0.52ms[/tex]
Next, calculate the rotation time to head up sector 1 on track 8 to sector 1 on track 9
This is calculated as:
[tex]r_t = t \times \frac{s-1}{s}[/tex]
So, we have:
[tex]r_t = \frac 16 \times \frac{32-1}{32}[/tex]
[tex]r_t = \frac 16 \times \frac{31}{32}[/tex]
[tex]r_t = 0.1615[/tex]
Convert to ms
[tex]r_t = 0.1615 \times 100[/tex]
[tex]r_t = 16.15[/tex]
So, the required time to transfer sectors is:
Time = 2 * Time to read/write to a sector + Seek time + Rotation time
This gives
[tex]Time = 2 \times 0.52 + 2 + 16.15[/tex]
[tex]Time = 19.19[/tex]
Hence, it will take 19.19 ms to transfer sector 1 on track 8 to sector 1 on track 9

In the following code segment, assume that the ArrayList numList has been properly declared and initialized to contain the Integer values [1, 2, 2, 3]. The code segment is intended to insert the Integer value val in numList so that numList will remain in ascending order. The code segment does not work as intended in all cases.
int index = 0;
while (val > numList.get(index))
{
index++;
}

For which of the following values of val will the code segment not work as intended?
a. 0
b. 1
c. 2
d. 3
e. 4
Answer:
e. 4
Explanation:
The code segment will not work as intended if the value of the variable val is 4. This is because the while loop is comparing the value of the variable val to the value of each element within the numList. Since there is no element that is bigger than or equal to the number 4, this means that if the variable val is given the value of 4 it will become an infinite loop. This would cause the program to crash and not work as intended.
The program illustrates the use of while loops.
The code segment will not work as intended when the value of val is 4
LoopsLoops are used to perform repeated operations
The programFrom the program, the while loop is repeated under the following condition:
val > numList.get(index)
This means that:
The loop is repeated as long as val has a value greater than the index of numList (i.e. 3)
From the list of options, 4 is greater than 3.
Hence, the code segment will not work as intended when the value of val is 4
