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

    static void Main(string[] args)
    {
        while(true)

            string width = new string('#', num[1]);

            for (int i = 0; i < num[0]; i++)
