例如:輸入 123,輸出321
- import java.util.Scanner;
- public class C1
- {
- public static void main(String[] args)
- {
- Scanner input = new Scanner(System.in);
- System.out.println("請入一個三位數:");
- int a = input.nextInt();
- int b = a / 100;
- int c = ( a - b * 100 ) / 10;
- int d = a - 100 * b - 10 * c;
- System.out.println("結果為:" + d + c + b);
- }
- }
