1、首先输入一正整数 2、可以将这个正整数转化成字符串 3、然后利用字符串的几种方法来将个"正整数"反序输出就行了 public class demo { public static void main(String[] args) { Scanner input = new Scanner(System.in); int n = input.next...

import java.util.Scanner; public class Qh{ public static void main(String[] args){ Scanner input=new Scanner(System.in); System.out.println("请输入:"); int a=input.nextInt(); int b=a/10000; int c=a%10000; int d=c/1000; int e=c...

#include "stdio.h" int main(void) { int x; scanf("%d", &x); if (x > 100) printf("%d", x + 10); else if (x < -10) printf("%d", -x + 10); else printf("0"); return 0; }
