过辣!（脑残人士的欢呼）

    long long x,y,n;
    cin>>x>>y>>n;
    cout<<n-x-y;

#include<bits/stdc++.h>
using namespace std;int main(){cout<<6;}

结束！ 已AC

#include <iostream>
using namespace std;
int main()
{
    int x,y,n;
    cin >> x >> y >> n;
    cout << n-x-y;
    return 0;
}

#include <iostream> using namespace std; int main() { int x,y,n; cin >> x >> y >> n; cout << n - x - y; return 0; }

#include <iostream> using namespace std; int main() { int x,y,n; cin >> x >> y >> n; cout << n - x - y; return 0;

#include <bits/stdc++.h> 
using namespace std;
int main(){
    cout<<6;
}

#include<bits/stdc++.h>
using namespace std;
int main()
{
    int a , b , c;
    cin >> a >> b >> c;
    c = c - a - b;
    cout << c;
    return 0;
}

so

#include <iostream> using namespace std; int main() { int x,y,n; cin >> x >> y >> n; cout << n - x - y; return 0; }

😄

#include <iostream>
using namespace std;
int main()
{
    int x,y,n;
    cin >> x >> y >> n;
    cout << n - x - y;
    return 0;
}
