HackerEarth Lunch boxes problem solution.

using namespace std;

const int MAX_N = 1e5 + 121;
int n, m;
int a[MAX_N];

void solve(){

cin >> n >> m;
for(int i = 1; i <= m; ++i){
cin >> a[i];

sort(a + 1,a + m + 1);

int cnt = 0;
int sum = 0;

for(int i = 1; i <= m; ++i){
sum += a[i];
if(sum <= n)++cnt; else break;

cout << cnt << endl;


int main(){


int t;
cin >> t;

return 0;

second solution

import sys

input = lambda: sys.stdin.readline().rstrip("\r\n")

t = int(input())
while t > 0:
t -= 1
n, m = map(int, input().split())
a = list(map(int, input().split()))
i = 0
while i < m and a[i] <= n:
n -= a[i]
i += 1
