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).
Code:
import java.util.Scanner;
public class ProjectDetails {
public static void removeDuplicates(char s[],int n) {
String result = "";
int i,j;
for(i=0; i<n; i++) {
for(j=0; j<n; j++) {
if(s[i]==s[j]) {
break;
}
}
if(i==j) {
result+=s[i];
}
}
int a = result.length();
if(a%2==0) {
System.out.println("CHAT WITH HER!");
}
else {
System.out.println("IGNORE HIM!");
}
}
public static void main(String[] args) {
Scanner sc = new Scanner (System.in);
char[] s = sc.next().toCharArray();
int n = s.length;
removeDuplicates(s,n);
}
}
