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

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