C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int n,m;
	cin>>n>>m;
	if(n*10<=m*18) cout<<"YES";
	else cout<<"NO\n"<<n*10-m*18;
	return 0;
}

Python :

# coding=utf-8
a=input().split()
x=int(a[0])
y=int(a[1])
if (x*10)<=(y*18) :
    print('YES')
else :
    print('NO')
    print((x*10)-(y*18))
