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;

public class Test
{
	public static void Main()
	{
		// your code goes here
		string[] s = Console.ReadLine().Split(' ');
		long[] n = new long[s.Length];
		for(int i = 0; i < s.Length; i++) {
			n[i] = long.Parse(s[i]);
		}
		
		while(n[0] != 0 || n[1] != 0) {
			for(int i = 0; i < n[0]; i++){
				for(int j = 0; j < n[1];j++){
					Console.Write("#");
				}
				Console.WriteLine();
			}
			
			Console.WriteLine();
			
			s = Console.ReadLine().Split(' ');
			for(int i = 0; i < s.Length; i++) {
				n[i] = long.Parse(s[i]);
			}
		}
		
	}
