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

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

int main() {
  
  int A=0, B=0, C=0;
  
  cin >> A >> B >> C;
  
  if(A==5 && B==5) {
    
    if(C==7) {
      
      cout << "YES" << endl;
      
    } else {
      
      cout << "NO" << endl;
      
    }
    
  } else if(A==5 && C==5) {
    
    if(B==7) {
      
      cout << "YES" << endl;
      
    } else {
      
      cout << "NO" << endl;
      
    }
    
  } else if(B==5 && C==5) {
    
    if(A==7) {
      
      cout << "YES" << endl;
      
    } else {
      
      cout << "NO" << endl;
      
    }
    
  } else if(A!=5 || A!=7) {
    
    cout << "NO" << endl;
    
  } else if(B!=5 || B!=7) {
    
    cout << "NO" << endl;
    
  } else if(C!=5 || C!=7) {
