题目:输入两个整数x,y,要求输出x的y次方的结果的最后三位数(y<100).

 1 import java.util.Scanner;
 2 
 3 public class Main{
 4 
 5     public static void main(String[] args) {
 6         Scanner sca = new Scanner(System.in);
 7         int x = sca.nextInt();
 8         int y = sca.nextInt();
 9         int re=1;
10         
11         for(int i=0;i<y;i++){
12             re = re*x;
13             if(re/1000>=1){
14                 re = re%1000;
15             }
16         }
17         String str = String.valueOf(re);
18         if(str.length()==1){
19             System.out.println("00"+str);
20         }else if(str.length()==2){
21             System.out.println("0"+str);
22         }else {
23             System.out.println(str);
24         }
25     }
26 }
