HackerRank Python Solution - Strings - Designer Door Mat

Mr. Vincent works in a doormat manufacturing company. One day, he designed a new doormat 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.

Sample Designs:

Input Format:

• A single line containing the space-separated values of N and M.

Constraints:

• 5 < N < 101
• 15 < M < 303

Output Format:

• Output the design pattern.

Sample Input:

9 27

Sample Output:

Solution:

# Enter your code here. Read input from STDIN. Print output to STDOUT

n,m= map(int,input().split())
center = n//2
count = -1
for i in range(0,n):
    
    if i == center:
        count += 2
        pattern = 'WELCOME'
        print(pattern.center(m,'-'))
        
    elif i < center:
        count += 2
        pattern = '.|.' * count
        print(pattern.center(m,'-'))
    
    elif i > center:
        count -= 2
        pattern = '.|.' * count
        print(pattern.center(m,'-'))
