输入一个整数，将这个整数以字符串的形式逆序输出 程序不考虑负数的情况...

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

    Scanner scanner = new Scanner(System.in);
    long l = scanner.nextLong();
    String string = String.valueOf(l);
    for (int i = string.length() - 1; i >= 0; i--) {
        System.out.print(string.charAt(i));
    }
}

}
