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

#include <bits/stdc++.h>
#define rep(i, n) for (int i = 0; i < (int)(n); i++)
#define REP(i, s, n) for (int i = (s); i < (int)(n); i++)
#define INF 100000000

using namespace std;

int main() {
   vector<int> v(3); 
   rep(i,3)
   cin >> v[i];
   sort(v.begin(),v.end()); 
   if(v[0]==5&&v[1]==5&&v[2]==7)
   cout << "YES" << endl;
   else 
   cout << "NO" << endl;
