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