算法学习--递归反转字符串

import java.util.Scanner;
public class exercise_reversal {
    public static void main(String [] args){
//        找重复  找变化  找出口
//        反转字符串
        Scanner input = new Scanner(System.in);
        System.out.println("请输入您要反转的字符串:");
        String i = input.next();
        int l = i.length()-1;
        System.out.print(reverse(i,l));
    }
    static String reverse(String chuan,int end){
        if(end==0)
            return ""+chuan.charAt(0);
        return chuan.charAt(end)+reverse(chuan,end-1);
    }
