Solution in C++14 (GCC 5.4.1) (judge verdict: Accepted)

#include <bits/stdc++.h>
#define  rep(i,n) for(int i=0;i<(n);i++)
using namespace std;
typedef long int li;
typedef unsigned long long ull;
typedef vector<int> vi;


int main()
{
    int A,B,C;
    cin>>A>>B>>C;
    if( (A==5 && B==7 && C==5)||
        (A==5 && B==5 && C==7)||
        (A==7 && B==5 && C==5) ) cout<<"YES\n";
    else cout<<"NO\n"; 

    return 0;
