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

        static void Main(string[] args)
        {
            for (int i = 1; 0<i; i++)
            {

                String[] str = Console.ReadLine().Split(' ');
                int W = int.Parse(str[0]);
                int H = int.Parse(str[1]);
                
                string line = "";

                if (W == 0 && H == 0)
                {
                    return;
                }
                for (int j = 0; j < H; j++)

                    line = line + "#";

                }
