The parameters list contain the array that is passed to and the size of the array respectively. Is there anywhere I could improve my code?void insertionSort(int a[], int s) {    for (int i = 0; i < s - 1; i++) {        int j = i + 1;        int key = a[j];        while (i >= 0 && a[i] > key) {            a[i+1] = a[i];            i--;        }        a[i+1] = key;    }}
