Those days, many boys use beautiful girls' photos as avatars in forums. So it is pretty hard to tell the gender of a user at the first glance. Last year, our hero went to a forum and had a nice chat with a beauty (he thought so). After that they talked very often and eventually they became a couple in the network. 

But yesterday, he came to see "her" in the real world and found out "she" is actually a very strong man! Our hero is very sad and he is too tired to love again now. So he came up with a way to recognize users' genders by their user names.

This is his method: if the number of distinct characters in one's user name is odd, then he is a male, otherwise she is a female. You are given the string that denotes the user name, please help our hero to determine the gender of this user by his method.
The first line contains a non-empty string, that contains only lowercase English letters — the user name. This string contains at most 100 letters.

using namespace std;

int main()
{
	char s[101];
 
	cin>>s;
	 int l  = strlen(s);
	sort(s,s+l);
	 int count =0;
    for(int i=0; i<l; i++)
    {
        if(s[i] != s[i+1])
        {
            count++;
        }
    }
    if(count%2==0)
    {
        cout<<"CHAT WITH HER!\n";
    }
    else
    {
        cout<<"IGNORE HIM!\n";
    }
}
