题目1224:整除的尾数

题目描述:

一个整数，只知道前几位，不知道末二位，被另一个整数除尽了，那么该数的末二位该是什么呢

代码:

package lanqiao; import java.util.*; public class Main { public static void main(String[] args) { Scanner sc = new Scanner(System.in); while(sc.hasNext()) { int a = sc.nextInt(); int b = sc.nextInt(); if(a == 0 && b == 0) { break; } StringBuffer sb = new StringBuffer(); int num = 0; for(int i = 0;i <= 9;i ++) { num = a * 100 + i; if(num % b == 0) { sb.append(String.format("0%d ",i)); } } for(int i = 10;i <= 99;i ++) { num = a * 100 + i; if(num % b == 0) { sb.append(String.format("%d ",i)); } } if(sb.length() > 0) { System.out.println(sb.substring(0,sb.length() - 1)); } } } }
