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

Sample Input

Solution in C# (judge verdict: Accepted)

using System;
using System.Collections;
using System.Collections.Generic;
class main{
	public static void Main(){
		int ct;
		int[] H = new int[100000];
		int[] W = new int[100000];
		for(ct = 0;; ct++)
		{
			string[] str = Console.ReadLine().Split(' ');
			H[ct] = int.Parse(str[0]);
			W[ct] = int.Parse(str[1]);
			if (H[ct] == 0 && W[ct] == 0)
			{
				break;
			}
		}
		for(int i = 0; i < ct; i++)
		{
			for(int j = 0; j < H[i]; j++)
			{
				for(int k = 0; k < W[i]; k++)
				{
					Console.Write('#');
				}
				Console.WriteLine();
			}
			Console.WriteLine();
