What Is The Value Stored In Sum4 After The Following Program Is #1998

 #include<stdio.h> int max_num(int a,int b) { if(a> b) return a; return b; } int maximum_subarray_sum(int *arr, int len) { int sum[len], idx; sum[0] = arr[0]; for(idx = 1; idx < len; idx++) sum[idx] = max_num(sum[idx - 1] + arr[idx], arr[idx]); int mx = sum[0]; for(idx = 0; idx < len; idx++) if(sum[idx] > mx) mx =sum[idx]; return mx; } int main() { int arr[] = {-2, 14, 11, -13, 10, -5, 11, -6, 3, -5},len = 10; int ans = maximum_subarray_sum(arr, len); printf("%d",ans); return 0; }
