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;

namespace PrintaRectangle
{
	class MainClass
	{
		public static void Main (string[] args)
		{
			while (true) {
				string[] tmp = Console.ReadLine ().Split (" ".ToCharArray ());
				int height, Wide;

				height = int.Parse (tmp [0]);
				Wide = int.Parse (tmp [1]);
				if (height == 0 && Wide == 0)
					break;

				for (int i = 0; i < height; i++) {
					for (int j = 0; j < Wide; j++) {
						Console.Write ("#");
					}
					Console.Write ("\n");
				}
				Console.Write ("\n");
			}
		}
	}
