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

Solution in C# (judge verdict: Accepted)

using System;

class Program
{
  public static void Main(string[] args)
  {
    while(true)
    {
      string[] read = Console.ReadLine().Split(' ');
      int H = int.Parse(read[0]);
      int W = int.Parse(read[1]);
      if(H == 0 && W == 0) break;
      for(int i = 0;i < H;i++)
      {
        for(int j = 0;j < W;j++)
        {
          Console.Write("#");
        }
        Console.WriteLine();
      }
      Console.WriteLine();
    }
  }
