# Mr. Vincent works in a door mat manufacturing company. One day, he designed a new door mat with the following specifications:
#
# Mat size must be NNXMM. (NN is an odd natural number, and MM is 33 times NN.)
# The design should have 'WELCOME' written in the center.
# The design pattern should only use |, . and - characters.
# Sample Designs
