In this **HackerRank Designer Door Mat problem solution in python**, 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.

## Problem solution in Python 2 programming.

N, M = map(int,raw_input().split()) # More than 6 lines of code will result in 0 score. Blank lines are not counted. for i in xrange(1,N,2): print 3*(N-i)/2*"-"+".|."*i+"-"*(3*(N-i)/2) print "-"*((3*N-7)/2)+"WELCOME"+"-"*((3*N-7)/2) for i in xrange(N-2,-1,-2): print (3*(N-i)/2)*"-"+".|."*i+"-"*(3*(N-i)/2)

## Problem solution in Python 3 programming.

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]))

### Problem solution in pypy programming.

N, M = map(int,raw_input().split()) for i in xrange(1,N,2): print "-"*(M/2-(3*i-1)/2)+ ".|."*((i-1)/2)+".|." + ".|."*((i-1)/2) + "-"*(M/2-(3*i-1)/2) print "WELCOME".center(M,"-") for i in xrange(N-2,-1,-2): print "-"*(M/2-(3*i-1)/2) + ".|."*((i-1)/2)+".|." + ".|."*((i-1)/2) + "-"*(M/2-(3*i-1)/2)
