Mr. AK works in a door mat manufacturing company. One day, he designed a new door mat with the following specifications:

  • Mat size must be X. ( is an odd natural number, and  is  times .)

  • The design should have 'WELCOME' written in the center.

  • The design pattern should only use |, . and - characters

  • Sample Designs
        Size: 7 x 21
        

Solution::


n,m=map(int,input().split())

pattern = [('.|.'*(2*i + 1)).center(m, '-') 

    for i in range(n//2)]

        print('\n'.join(pattern + 

        ['WELCOME'.center(m, '-')] 

        + pattern[::-1]))
