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 ITP1_5_A
{
    public static void Main()
    {
        int[] H = new int[10000];
        int[] W = new int[10000];
        int count = 0;

        for (; ; count++)
        {
            string[] Input = Console.ReadLine().Split(' ');
            if (Input[0] == "0" && Input[1] == "0")
                break;
            H[count] = int.Parse(Input[0]);
            W[count] = int.Parse(Input[1]);
        }

        for (int k = 0; k < count; k++)
        {
            for (int i = 0; i < H[k]; i++)
            {
                for (int j = 0; j < W[k]; j++)
                {
                    Console.Write("#");
                }
