AcWing 1208. 翻硬币
【思路】
题目说一定有解，那只要将原状态往目标状态翻就一定可以达到要求。

import java.util.Scanner;
public class Main{
    public static void change(char [] c1,int i){
        if(c1[i]=='*') c1[i] = 'o';
        else c1[i] = '*';
    }
    public static void main(String args[]){
        Scanner reader = new Scanner(System.in);
        String s1 =reader.next();
        String s2 =reader.next();
        char [] c1 = s1.toCharArray();
        char [] c2 = s2.toCharArray();
        int cnt = 0;
        for(int i = 0; i < c1.length - 1; i++){
            if(c1[i] != c2[i]){
                cnt++;
                change(c1,i);
                change(c1,i+1);
                
            }
        }
        System.out.println(cnt);
        
    }
}
