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;

public class Test
{
	public static void Main()
	{
            string[] data;
            int H, W;
            while(true){

                data = Console.ReadLine().Split();
                if (int.Parse(data[0])== 0 && int.Parse(data[1]) == 0)
                {
                    break;
                }

                for (H = int.Parse(data[0]); H > 0; H--)
                {
                    for (W = int.Parse(data[1]); W > 0; W--)
                    {
                        Console.Write("#");
                    }
                    Console.WriteLine();
                }
