Solution in JAVA (judge verdict: Wrong Answer)

import java.util.Scanner;

public class Main{
	public static void main(String[] args){
        
        Scanner sc = new Scanner(System.in);
        long a,b,i,j;
		while(true){
        a = sc.nextInt();
        b = sc.nextInt();
            if(a==0||b==0)break;
		for(i=0;i<a;i++){
            for(j=0;j<b/2;j++){
            if(a!=b)System.out.print("#");
        }
      System.out.println();  
        }
        }
   }
