    int t;
    cin >> t;
    while (t--) {
        string s;
        cin>>s;
        sort(s.begin(),s.end());
        cout<<s<<endl;

Java解答

import java.util.Arrays;
import java.util.Scanner;

public class Main {
   public static void main(String[] args) {
	  Scanner s = new Scanner(System.in) ;
	  
	  int n = s.nextInt() ;
	  
	  for (int i = 0; i < n; i++) {
		 String str = s.next() ;
		 
		 char[]c = str.toCharArray() ;
		 
		 Arrays.sort(c) ;
		 
		 for (int j = 0; j < c.length; j++) {
		    System.out.print(c[j]) ;	
		 }
		 System.out.println();
	  }
   }
