Given the following sort

void sortRec(vector& A, int n) {

if (n==1)

return;

sortRec(A, n - 1);

int i;

int tmp = A[n - 1];

i = n-1;

while (i>0 && A[i-1] >tmp) {

A[i] = A[i-1];

i--; }

A[i] = tmp;

}

Modify the function so the number of comparisons are counted Write a program that will

Generate 3 vectors for an inputted size o One vector for the best case o One vector for the worst case o One vector for the average case

For the best and worst case vector only run the sort once to get the count

For the average case you will have to run the sort serval times(100) on different ordered values in the vector and calculate the average number of comparisons Once you have all your counts for the three cases print them. For size X Number of comparisons for best case is X Number of comparisons for worst case is X Number of comparisons for average case is X

use C++
