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

                var a = int.Parse(sss[0]);
                var b = int.Parse(sss[1]);
                if (a == 0 && b == 0) break;
                for(var i=0;i<a;i++)
