#include <iostream>

直接return 0就可以了

#include <iostream>
using namespace std;
int main() {
    int k, sum = 0, N = 0;
    cin >> k;
    for (int i = 1; ; i++) {
        for (int j = 1; j <= i; j++) {
            if (N < k) {
                sum += i;
                N++;
            }
            else {
                cout << sum;
                return 0;
            }
        }
    }
    return 0;
}
