How many times is the function recursive_min_element() called when the following code is executed?
int min_of_two(int a, int b)
{
if(a < b)
return a;
return b;
}
int recursive_min_element(int *arr, int len, int idx)
{
if(idx == len - 1)
return arr[idx];
return min_of_two(arr[idx], recursive_min_element(arr, len, idx + 1));
}
int main()
{
int n = 10, idx = 0, arr[] = {5,2,6,7,8,9,3,-1,1,10};
int min_element = recursive_min_element(arr,n,idx);
printf("%d",min_element);
return 0;
}
int min_of_two(int a, int b)
{
if(a < b)
return a;
return b;
}
int recursive_min_element(int *arr, int len, int idx)
{
