# HackerEarth Maximum Sum problem solution

In this HackerEarth Maximum Sum problem solution, You are given an array of integers A, you need to find the maximum sum that can be obtained by picking some non-empty subset of the array. If there are many such non-empty subsets, choose the one with the maximum number of elements. Print the maximum sum and the number of elements in the chosen subset.

## HackerEarth Maximum Sum problem solution.

`#include<bits/stdc++.h>using namespace std;int main() {  int n;  cin >> n;  long long sum = 0;  int cnt = 0;  int mx = -2e9;  for(int i = 1; i <= n; i++) {    int x;    scanf("%d", &x);    if(x >= 0) sum += 1LL * x, cnt++;    mx = max(mx, x);  }  if(cnt) cout << sum << " " << cnt << endl;  else cout << mx << " " << 1 << endl;  return 0;}`
