C++ Guide (C++17)

C++ submissions compile with g++ -O2 -std=c++17. Output checking is case-insensitive unless the problem statement says otherwise.

Judge Assumptions

• Use stdin and stdout only.
• No file I/O and no network access.
• For interactive problems, flush after each command.
• All supported languages are calibrated for fairness.

Template

#include <bits/stdc++.h>
using namespace std;

int main() {
    ios::sync_with_stdio(false);
    cin.tie(nullptr);

    int a;
    int b;
    cin >> a >> b;
    cout << (a + b) << '\n';
    return 0;
}
