小O的字符 （Java代码）

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Demo1791 {

public static void main(String[] args) {

            Scanner in=new Scanner(System.in);

            while(in.hasNext()){

                judge(in.nextLine(),in.nextLine());

            }}

private static void judge(String a,String b){

            int[] ac=new int[127];int[] bc=new int[127];

            for(int i=0;i<a.length();i++)ac[a.charAt(i)]++;

            for(int i=0;i<b.length();i++)bc[b.charAt(i)]++;

                    boolean z=false,f=false;

            for(int i=0;i<127;i++){

                    ac[i]-=bc[i];

                    if(ac[i]<0)f=true;

                    if(ac[i]>0)z=true;

            }

            if(z&&f)System.out.println("a!=b");

            else if(z&&!f)System.out.println("a>=b");

            else if(!z&&f)System.out.println("a<=b");

            else if(!z&&!f)System.out.println("a==b");

             }

}
