【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.LinkedList;
import java.util.List;
import java.util.Scanner;
public class Demo36 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("输入数字个数n：");
int n = in.nextInt();
System.out.println("输入后移位数m：");
int m = in.nextInt();
LinkedList<Integer> list = new LinkedList<Integer>();
for (int i = 0; i < n; i++) {
System.out.println("请输入第"+(i+1)+"个数:");
list.add(in.nextInt());
}
System.out.println("原数据排序为：");
for (int t : list) {
System.out.print(t + " " );
}
System.out.println();
List<Integer> temp1 = list.subList(list.size() - m, list.size());
List<Integer> temp2 = list.subList(0, list.size() - m);
temp2.addAll(0, temp1);
System.out.println("移动后排序为：");
for (int t : temp2) {
System.out.print(t + " " );
}
}
}
或
import java.util.*;
public class Demo36{
public static void main(String[] args){
Scanner in=new Scanner(System.in);
System.out.println("请定义数组的长度：");
int n=in.nextInt();
System.out.println("请输入移动的位数：");
int m=in.nextInt();
int [] arr=new int [n];
int [] brr=new int [n];
for(int i=0;i<n;i++){
System.out.println("请输入第"+(i+1)+"个数：");
arr[i]
=in.nextInt();
}

System.out.println("排序前：");
for(int i=0;i<n;i++){
System.out.print(arr[i]+" ");
}
System.out.pri
