Problem: 

Interaction

This is an interactive problem. You need to read participants' queries from standard input and print your responses to standard output. You don't know the number of queries upfront, so you'll need to process them as you get them; you'll know you're done once you reach the end of the file.

In each query, you will be asked the question, written in one line. You have to answer it correctly, patiently and without any display of emotions. Your response is case-insensitive.

Please make sure to use the stream flushing operation after each response in order not to leave part of your output in some buffer.

Example

Input


Is it rated?
Is it rated?
Is it rated?


Output


NO
NO
NO

Solution (in CPP):

Solution:
#include<bits/stdc++.h>
#define F(i,L,R) for (int i = L; i < R; i++) //next four are for "for loops"
#define FE(i,L,R) for (int i = L; i <= R; i++)
#define FF(i,L,R) for (int i = L; i > R; i--)
#define FFE(i,L,R) for (int i = L; i >= R; i--)
#define getI(a) scanf("%d", &a) //next three are handy ways to get ints, it's also force you to use '&' sign
#define getII(a,b) scanf("%d %d", &a, &b)
#define getIII(a,b,c) scanf("%d %d %d", &a, &b, &c)
#define whileZ() int T; getI(T); while(T--)
#define wez(n) int (n); scanf("%d",&(n)) //handy if the input is right after the definition of a variable
#define wez2(n,m) int (n),(m); scanf("%d %d",&(n),&(m))
#define wez3(n,m,k) int (n),(m),(k); scanf("%d %d %d",&(n),&(m),&(k))
#define ll long long

int main(){
    string str;
    while(getline(cin, str)){
        if(str.compare("Is it rated?") == 0)
        cout<<"NO"<<'\n';
        fflush(stdout);
    }
