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

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

int main()
{
  	int a, b, c;
  	cin>>a>>b>>c;
  	if(a > 10 || a < 1 || b > 10 || b < 1 || c > 10 || c < 1)
      exit(0);
  	if((a == 5 && b == 5 && c == 7) || (a == 5 && b == 7 && c == 5) ||
      (a == 7 && b == 5 && c == 5))
      cout<<"YES\n";
 	else
      cout<<"NO\n";
  	/*int aa[20];
  	for(int i = 0; i < 20; i++)
    {
      	aa[a]++;
      	aa[b]++;
      	aa[c]++;
    }
  	if(aa[5] == 2 && aa[7] == 1)
      cout<<"YES\n";
  	else
      cout<<"NO\n";*/
	return 0;
