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

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

#define boost ios::sync_with_stdio(0); cin.tie(0);
#define int long long
const int N = 1e5 + 10;
const int MOD = 1e9 + 7;

int32_t main(){
    boost;
 

   int a[3];

   for(int i = 0 ; i < 3 ; ++i)
   	cin >> a[i];

   sort(a,a+3);


   if(a[0] == 5 && a[1] == 5 && a[2] == 7)
   	cout << "YES";
   else
   	cout << "NO";

    return 0;
