#include<iostream>
using namespace std;
signed main(){

水题。计算判断即可 AC。

#include<bits/stdc++.h>
#define int long long
#define INF 0x3f3f3f
using namespace std;
int x,y;
signed main(){
	cin>>x>>y;
	if(x*10>y*18)cout<<"NO\n"<<x*10-y*18;
	else cout<<"YES";
	return 0;
}

秒杀。

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

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))
