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;

class MyClass
{
    static string Repeat(string str, int repeat)
    {
        string str2 = "";
        for (int i = 0; i < repeat; i++)
        {
            str2 += str;
        }
        return str2;
    }

    static void Main(string[] args)
    {
        string str;
        while ((str = Console.ReadLine()) != "0 0")
        {
            int h = int.Parse(str.Split(' ')[0]);
            int w = int.Parse(str.Split(' ')[1]);
            for (int i = 0; i < h; i++)
            {
                Console.WriteLine(Repeat("#", w));
            }
            Console.WriteLine();
        }
    }
