Boy or Girl

那些日子，许多男孩在论坛上使用漂亮女孩的照片作为化身。所以很难在第一眼就知道用户的性别。去年，我们的英雄去了一个论坛，和一位美女聊天（他想是这样）。之后，他们经常交谈，最终他们成为了网络中的一对情侣。 但是昨天，他在现实世界里看到了“她”，发现“她”其实是一个非常强壮的男人！我们的英雄很伤心，他太累了，不能再爱了。因此，他想出了一种通过用户名来识别用户性别的方法。 这是他的方法：如果用户名中的不同字符数是奇数，那么他是男性，否则她是女性。您给出了表示用户名的字符串，请用我们的方法帮助我们的英雄确定这个用户的性别。 如果是女生，输出 `CHAT WITH HER!`；如果是男生，则输出`IGNORE HIM!`。 翻译提供者：友利奈绪

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.

If it is a female by our hero's method, print "CHAT WITH HER!" (without the quotes), otherwise, print "IGNORE HIM!" (without the quotes).

CHAT WITH HER!

IGNORE HIM!

CHAT WITH HER!

For the first example. There are 6 distinct characters in "wjmzbmr". These characters are: "w", "j", "m", "z", "b", "r". So wjmzbmr is a female and you should print "CHAT WITH HER!".
