Question:

(Assume all the characters are given in lower case).
Note: In the String “programming” the characters m or r or g is repeated.
Sample input 1:

Sample output:
vole
Sample input 2:
programming
Sample output 2:
Rponmiga
Code:
Main.java
import java.util.Arrays;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String str = sc.next();
char ch[] = str.toCharArray();
Arrays.sort(ch);
int n = ch.length;
for (int i=0;i<n;i++){
for (int j=i+1;j<n;j++) {
if (ch[i] == ch[j]) {
ch[i] = '*';
}
}
}
String string = "";
for (int i=n-1;i>=0;i--){
if(ch[i]!='*'){
string +=ch[i];
}
}
System.out.println(string);
}
}Output:
programming rponmiga
