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
{
    static void Main(string[] args)
    {
        while (true)
        {
            string[] data = Console.ReadLine().Split(' ');
            int H = int.Parse(data[0]);
            int W = int.Parse(data[1]);
            if (H == 0 && W == 0)
            {
                return;
            }

            string line = "";
            for (int i = 0; i < W; i++)
            {
                line = line + "#";
            }
            for (int i = 0; i < H; i++)
            {
                Console.WriteLine(line);
            }
            Console.WriteLine();
        }
    }
