if 判断，秒了

#include <bits/stdc++.h>

    cin >> a >> b >> c;
    if (a + b > c && a + c > b && b + c > a) cout << 1;
    else cout << 0;
    return 0;
}

#include<bits/stdc++.h> using namespace std; int main(){ int a,b,c; cin>>a>>b>>c; if (a+b>=c and a+c>=b and b+c>=a) {cout<<1;} else {cout<<0;} return 0; } //自己换行
