Problem:
Print a Rectangle

Draw a rectangle which has a height of H cm and a width of W cm. Draw a 1-cm square by single '#'.

Input

The input consists of multiple datasets. Each dataset consists of two integers H and W separated by a single space.

The input ends with two 0 (when both H and W are zero).

Output

For each dataset, print the rectangle made of H × W '#'.

Print a blank line after each dataset.

Constraints

1 ≤ H ≤ 300

1 ≤ W ≤ 300

using System;

namespace ITP_5_A{
    public class Program{
        public static void Main(string[] args){
            bool loopFlag = true;

            while(loopFlag){
                string[] temp = Console.ReadLine().Split(' ');
                int y = int.Parse(temp[0]);
                int x = int.Parse(temp[1]);

                if(x==0 && y==0){
                    loopFlag = false;
                }else{
                    //???????????????????????????
                    for(int h=0;h<y; h++){
                        for(int w=0;w<x; w++){
                            Console.Write("#");
                        }
