今天美菜网的笔试第二题，大佬们有什么样的思路吗
我只AC了33%，也就是样例我给完成了
我的做法是
package com.study.Java;
import java.util.*;
public class Main {
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
String s=sc.nextLine();
System.out.print(DestoryText(s));
}
private static String DestoryText(String s) {
// TODO Auto-generated method stub
char[] c=s.toCharArray();
StringBuffer sb=new StringBuffer(s);
int a=0,b=0;
for( int i=0;i<c.length;i++)
{
if(c[i]=='$') a=i;
if(c[i]=='#') b=i;
}
if(a==0&&b==0)return sb.toString();
String sub1=sb.substring(0, a);
if(b==0) {
String sub2=sb.substring(a+1, c.length);
return sub2+sub1;
}
String sub2=sb.substring(a+1, b);
String sub3=sb.substring(b+1, c.length);
/**System.out.println(sub1);
System.out.println(sub2);
System.out.println(sub3);**/
return sub2+sub1+sub3;
}
}
