【程序36】

题目：有n个整数，使其前面各数顺序向后移m个位置，最后m个数变成最前面的m个数 import java.util.Scanner;

public class lianxi36 {

public static void main(String[] args) {

int N =10;

int[] a = new int[N];

Scanner s = new Scanner(System.in);

System.out.println("请输入10个整数：");

for(int i=0; i<N; i++) {

a[i] = s.nextInt();

}

System.out.print("你输入的数组为：");

for(int i=0; i<N; i++) {
