Answer in Java Tim while preparing for his CAT exam, was studying the topic Number Systems. He encountered a loving da question: Given a number N, find the number of pairs (cy) where both x and y are less than N and Highent Common Factor(HCF) of x and y is 1. You have to solve the question for him. Note: 0 can be included within the pairs Input Specification: Input: The number N from which the pairs (x,y) should be obtained Output Specification: Return the total number of pairs Example 1: input1: 4 Output: 9 Explanation: The pairs can be (1,0) ,(0,1) (1,1) (1,2) (2,1) (0, 3) (3,1) (2,3) (0,2) So, a total of 9 pairs

Figure 2 void sort_Algo (int anArray[], int n) { int i, j, idx; for (i = 0; i anArray[ idx ]) idx = j; Swap (anArray[ idx ], anArray[ i ]); } } int main() { const int n = 8; int anArray[n] { -9, 14, 52, 106, 22, -1, 99}; sort_Algo(anArray, n); } Name the sorting algorithm exercised by the sort_Algo() function. * Your answer Determine if anArray[] is to be sorted into ascending, or descending order. Your answer Trace the sorting algorithm in Figure 2 as it sorts anArray[]. (Answer the question according to the format, eg. Pass 0:3, 3, 3; Pass 1: 3, 3, 3; Pass2: 3, 3, 3;) * Your answer
12.14 Zylab 3 - Single Procedure Call Given an array of at least one integer, write a program to create a new array with elements equal to the power of each element in the original array raised to the index, i.e., P[i] = A[i]^i. For this, write two functions that will be called in main function independently. ● power inputs: element (A[i]) and index (1) • task: returns the value of element raised to index (A[i]^i). } O • newElement inputs: base address of new array P (*P), current size of P (variable k) and the new element (A[i]^i) o task: add the new element at the end. o This function does not return any value (void). O Following is a sample C code to perform the required task. You may modify the code for the functions, but the task performed should not be changed. int main() { // Variable Declaration int *A, *P; int n, k; int pow; // Task of main function P[0] 1; for (int j = k = j; pow // Base addresses of A and P // Lengths of arrays A and B // Return value from power function }…
