Each of the parts a. through c. below is preceded by a comment indicating what the code should do. There is a least one problem with each section of code and it fails to do what was intended. Show how to modify or rewrite the code the code so that it does work as intended. If there are multiple problems, correct each one. Assume that all variables used have already been declared.
a. // INTENT: given an array arr of int values // set small equal to the smallest of the array values small = arr[0]; for (int j = 0; j < arr.length-1; j++) if (small
b. // INTENT: compute the average of all n values in the integer array arr; 1/ compute the average as a double and store it in the double variable avg int sum = 0; int n = arr.length; for (int k = arr.length; k <= 0; k--) sum = sum + arr[k]; double avg = sum /n; c. //INTENT: the array b should have the values of array a in reverse order int[] a = {1,2,3,4,5); int[] b = new int[5]; for (int i=0; i<=a.length; i++) b[i-1] = a[a.length-i];
Answer:
The correction is as follows:
(a)
small = arr[0];
for (int j = 0; j < arr.length; j++){
if (small > arr[j]) {
small = arr[j]; } }
(b)
double sum = 0;
int n = arr.length;
for (int k = arr.length-1; k >= 0; k--)
sum = sum + arr[k];
double avg = sum /n;
(c)
int[] a = {1,2,3,4,5};
int[] b = new int[5];
for (int i=0; i<a.length; i++)
b[i] = a[a.length-i-1];
Explanation:
Required
Correct each of the given code
a.
This line is correct; it initializes the smallest to the first element
small = arr[0];
This iterates through the array; however, the last element is left out.
for (int j = 0; j < arr.length-1; j++)
So, the correct code is: for (int j = 0; j < arr.length; j++){
The expected remaining part of the program which compares the elements of the array is missing
I've completed the code [See the answer section]
b.
By syntax this line is correct. However, for the average to be calculated as double; sum has to be declared as double
int sum = 0;
So, the correct code is: double sum = 0;
This line correctly calculates the length of the array
int n = arr.length;
This iteration will create an endless loop
for (int k = arr.length; k <= 0; k--)
So, the correct code is: for (int k = arr.length-1; k >= 0; k--)
This correctly add up the elements of the array
sum = sum + arr[k];
This correctly calculate the average of the array elements
double avg = sum /n;
(c)
The array a is incorrectly initialized because there is no matching end curly brace
int[] a = {1,2,3,4,5);
So, the correct code is: int[] a = {1,2,3,4,5};
This correctly create array b with 5 elements
int[] b = new int[5];
This iterates through a; however, the last element is left out
for (int i=0; i<=a.length; i++)
So, the correct code is: for (int i=0; i<a.length; i++)
This will create an out of bound error
b[i-1] = a[a.length-i];
So, the correct code is: b[i] = a[a.length-i-1];

int nums[10]; // Declare an array of 10 integers
int i, max;
printf("Enter 10 numbers: ");
for (i = 0; i < 10; i++) {
scanf("%d", &nums[i]); // Read in the numbers
}
max = nums[0]; // Initialize max to the first number in the array
for (i = 1; i < 10; i++) {
if (nums[i] > max) { // Compare each number to the current max
max = nums[i]; // If a number is larger, update the max
}
}
printf("The highest value is: %d", max);
return 0;

You had learnt how to create the Pascal Triangle using recursion.
def pascal(row, col):
if col == 1 or col == row:
return 1
else:
return pascal(row - 1, col) + pascal(row - 1, col - 1)
But there is a limitation on the number of recursive calls. The reason is that the running time for recursive Pascal Triangle is exponential. If the input is huge, your computer won't be able to handle. But we know values in previous rows and columns can be cached and reused. Now with the knowledge of Dynamic Programming, write a function faster_pascal(row, col). The function should take in an integer row and an integer col, and return the value in (row, col).
Note: row and col starts from 1.
Test Cases:
faster_pascal(3, 2) 2
faster_pascal(4, 3) 3
faster_pascal(100, 45) 27651812046361280818524266832
faster_pascal(500, 3) 124251
faster_pascal(1, 1) 1
def faster_pascal(row, col):
if (row == 0 or col == 0) or (row < col):
return 0
arr = [[0 for i in range(row+1)] for j in range(col+1)]
arr[0][0] = 1
for i in range(1, row+1):
for j in range(1, col+1):
if i == j or j == 0:
arr[i][j] = 1
else:
arr[i][j] = arr[i-1][j] + arr[i-1][j-1]
return arr[row][col]

With the given code, The code outputs 24.
How is this code run?On the first iteration, c is 1 and sum is 0, so c is incremented to 3 and sum is incremented to 3.
On the second iteration, c is 3 and sum is 3, so c is incremented to 5 and sum is incremented to 8.
On the third iteration, c is 5 and sum is 8, so c is incremented to 7 and sum is incremented to 15.
On the fourth iteration, c is 7 and sum is 15, so c is incremented to 9 and sum is incremented to 24.
At this point, c is no longer less than 10, so the while loop exits and the final value of sum is printed, which is 24.

Flowchart of Accepts as input the mass, in grams, and density, in grams per cubic centimeters, and outputs the volume of the object using the formula: density 1⁄4 mass / volume.
Below is a simple flowchart that shows the process of calculating the volume of an object using its mass and density:
+-----------------------------+
| Input: Mass (m), |
| Density (d) |
+-----------------------------+
|
|
+-----------------------------+
| Volume = Mass / Density |
+-----------------------------+
|
|
+-----------------------------+
| Output: Volume (v) |
+-----------------------------+
What is the Flowchart about?The flowchart I provided shows the basic process of calculating the volume of an object using its mass and density. The process starts with the input of the object's mass and density. The mass is typically given in grams and the density is given in grams per cubic centimeter.
The next step is to calculate the volume of the object. This is done by using the formula for density, which states that density is equal to mass divided by volume. So, to find the volume, we divide the mass of the object (in grams) by its density (in grams per cubic centimeter). This formula can be written as:
volume = mass / density
Finally, the calculated volume is then output, which is typically given in cubic centimeters.
Note that:
density = mass/volume.
Density = mass / volume

which component of cpu controls the overall operation of computer..
Answer:
Control unit.
Explanation:
A scheduling computer system refers to an ability of the computer that typically allows one process to use the central processing unit (CPU) while another process is waiting for input-output (I/O), thus making a complete usage of any lost central processing unit (CPU) cycles in order to prevent redundancy.
Modern central processing units (CPUs) only require a few nanoseconds to execute any instruction when all operands are stored in its registers.
In terms of the scheduling metrics of a central processing unit (CPU), the time at which a job completes or is executed minus the time at which the job arrived in the system is known as turnaround time.
Generally, it is one of the scheduling metrics to select for optimum performance of the central processing unit (CPU).
The component of the central processing unit (CPU) that controls the overall operation of a computer is the control unit. It comprises of circuitry that makes use of electrical signals to direct the operations of all parts of the computer system. Also, it instructs the input and output device (I/O devices) and the arithmetic logic unit how to respond to informations sent to the processor.

4. (15 points) Give an algorithm that takes as input a positive integer n and a number x, and computes xn (i.e., x raised to the power n) by performing O(lgn) multiplications. Your algorithm CANNOT use the exponentiation operation, and may use only the basic arithmetic operations (addition, subtraction, multiplication, division, modulo). Moreover, the total number of basic arithmetic operations used should be O(lgn).
Answer:
The algorithm is as follows:
Exponent(x, n):
if(n == 0):
return 1
pr = Exponent(x, int(n / 2))
if (n % 2 == 0):
Return pr* pr
else:
if(n > 0):
Return x * pr* pr
else:
Return (pr* pr) / x
Explanation:
In order to get a O(log n) time complexity, a recursive procedure is implemented by the algorithm
The algorithm begins here
Exponent(x, n):
If n is 0, the procedure returns 1
if(n == 0):
return 1
This recursively calculates the product of x, n/2 times
pr= Exponent(x, int(n / 2))
If n is even, the square of prod (above) is calculated
if (n % 2 == 0):
Return pr* pr
If otherwise (i.e. odd)
else:
If n is above 0, the square of prod multiplied by x is calculated
if(n > 0):
Return x * pr* pr
If otherwise, the square of prod divide by x is calculated
else:
Return ([tex]pr* pr[/tex]) / x
The time complexity is: O(log|n|)
