Problem: 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.

Input

The first line contains a non-empty string, that contains only lowercase English letters — the user name. This string contains at most 100 letters.

Output

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

Examples

Input

wjmzbmr


Output

CHAT WITH HER!


Input

xiaodao


Output

IGNORE HIM!


Input

sevenkplus


Output

CHAT WITH HER!

Note

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!".

Useful List Methods:

append()        Adds an element at the end of the list
clear()         Removes all the elements from the list
copy()          Returns a copy of the list
count()         Returns the number of elements with the specified value
extend()        Add the elements of a list (or any iterable), to the end of the current list
index()         Returns the index of the first element with the specified value
insert()        Adds an element at the specified position
pop()           Removes the element at the specified position
remove()        Removes the first item with the specified value
reverse()       Reverses the order of the list
sort()          Sorts the list

Useful Dictionary Methods:

clear()         Removes all the elements from the dictionary
copy()          Returns a copy of the dictionary
fromkeys()      Returns a dictionary with the specified keys and value
get()           Returns the value of the specified key
items()         Returns a list containing a tuple for each key value pair
keys()          Returns a list containing the dictionary's keys
pop()           Removes the element with the specified key
popitem()       Removes the last inserted key-value pair
setdefault()    Returns the value of the specified key. If the key does not exist: insert the key, with the specified value
update()        Updates the dictionary with the specified key-value pairs
values()        Returns a list of all the values in the dictionary

Input methods for faster access:

Single line input for multiple variables:  -->>  n,k=map(int, input().split())
Single line array imput:                   -->>  arr = [int(a) for a in input().strip().split(' ')]
Sorting in ascending order:                -->> arr.sort()
Sorting in descending order:               -->> arr.sort(reverse=True)
