What is the output of the following code?
#include<stdio.h>
int recursive_search_num(int *arr, int num, int idx, int len)
{
if(idx == len)
return -1;
if(arr[idx] == num)
return idx;
return recursive_search_num(arr, num, idx+1, len);
}
int main()
{
int arr[8] ={-11,2,-3,0,3,5,-6,7},num = -2,len = 8;
int indx = recursive_search_num(arr,num,0,len);
printf("Index of %d is %d",num,indx);
return 0;
}
