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

Sample Input

namespace Ex160506_1{
    public class Program{
        public static void Main(string[] args){
            while(true){
                var input = Console.ReadLine().Split(' ');
                var h = int.Parse(input[0]);
                var w = int.Parse(input[1]);

                if(h + w == 0) break;
                Enumerable.Repeat(Enumerable.Repeat('#', w).ToArray(), h).ToList().ForEach(Console.WriteLine);
                Console.WriteLine();
            }
        }
    }
