What is the output of the following code?

#include<stdio.h>
int max_of_two(int a, int b)
{
      if(a > b)
        return a;
      return b;
}
int min_of_two(int a, int b)
{
      if(a < b)
        return a;
      return b;
}
int recursive_max_element(int *arr, int len, int idx)
{
      if(idx == len - 1)
      return arr[idx];
      return max_of_two(arr[idx], recursive_max_element(arr, len, idx + 1));
}
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 max_element = recursive_max_element(arr,n,idx);
    int min_element = recursive_min_element(arr,n,idx);
    printf("%d %d",max_element,min_element);
    return 0;
}
