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)

public partial class IntroductionToProgramming{
	public static void Main(){
		string[] line = System.Console.ReadLine().Split(' ');

		int h = int.Parse(line[0]);
		int w = int.Parse(line[1]);

		while (!(h == 0 && w == 0))
		{
			string s = new string('#', w);
			for (int i = 0; i < h; i++ )
			{
				System.Console.WriteLine(s);
			}
			System.Console.WriteLine(string.Empty);

			string[] line2 = System.Console.ReadLine().Split(' ');

			h = int.Parse(line2[0]);
			w = int.Parse(line2[1]);
		}
	}
