Print a Frame
Draw a frame which has a height of H cm and a width of W cm. For example, the following figure shows a frame which has a height of 6 cm and a width of 10 cm.
########## #........# #........# #........# #........# ##########
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).
For each dataset, print the frame made of '#' and '.'.
Print a blank line after each dataset.
