Task
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 N X M. (N is an odd natural number, and M is 3 times N.)
The design should have ‘WELCOME’ written in the center.
The design pattern should only use |, . and – characters.

Solution:
n, m = map(int,input().split())
for i in range(n//2):
j = int((2*i)+1)
print(('.|.'*j).center(m, '-'))
print('WELCOME'.center(m,'-'))
for i in reversed(range(n//2)):
j = int((2*i)+1)
print(('.|.'*j).center(m, '-'))
Steps Used in solving the problem -
Step 1: First we have taken the input of n & m.
Step 2: then, we created a for loop to print the first half part.
Step 3: then, we printed the welcome line in the center.
Step 4: in last, we created another for loop to print the last half part.
