What is the output of the following implementation of Kadane's algorithm? #include int max_num(int a, int b) if(a > b) return a; return b; int kadane_algo(int *arr, int len) int ans, sum, idx; ans =0; sum =0; for(idx =0; idx < len; idx++) sum = max_num(0,sum + arr[idx]); ans = max_num(sum,ans); return ans; int main() int arr[] = -2, -3, -3, -1, -2, -1, -5, -3,len = 8; int ans = kadane_algo(arr,len); printf("%d",ans); return 0;
