문제

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 NXM. (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.

    Size: 7 x 21 
    ---------.|.---------
    ------.|..|..|.------
    ---.|..|..|..|..|.---
    -------WELCOME-------
    ---.|..|..|..|..|.---
    ------.|..|..|.------
    ---------.|.---------

 

=> 사이즈 주면, 도배장판 만들어! ., |, - 만 이용해서. 가운데 줄에는 WELCOME이 들어가야함

 

 

 

 

코드

---

N, M = map(int,input().split())


for i in range(N//2):
    print(
        ((".|.") * (2*i+1)).center(M, '-')
    )
    
    
print(
    "WELCOME".center(M,'-')
)


for i in range(N//2, 0, -1):
    print(
        ((".|.") * (2*i -1)).center(M, '-')
    )

 

 

 

 

노트

---

N, M = map(int,input().split()) # INPUT 값 받아오기
print(N, M) # 7 21

 

for i in range(N//2): # 윗 줄(.|. 가 늘어나는)
    print(
        ((".|.") * (2*i+1)).center(M, '-')
    )

OUTPUT

---------.|.---------
------.|..|..|.------
---.|..|..|..|..|.---

 

print(
    "WELCOME".center(M,'-') # 가운데 줄, WELCOME이 쓰이는 줄
)

 

for i in range(N//2, 0, -1): # 아랫줄(.|.가 줄어드는)
    print(
        ((".|.") * (2*i -1)).center(M, '-') # 윗줄과 대칭이 되게끔 조정
    )

• range([시작수], [끝 수], [간격]) 으로 N//2(=3) 부터 0 직적까지, -1씩 차이나게 i 반복.
• 3, 2, 1 을 거침

OUTPUT

---.|..|..|..|..|.---
------.|..|..|.------
---------.|.---------

 

 

정리좀 하면

N, M = map(int, input().split())

for i in range(1, N, 2):
    print(
        ('.|.' * i).center(M, '-')
    )

print('WELCOME'.center(M, '-'))

for i in range(N-2, 0, -2):
    print(
        ('.|.' * i).center(M, '-')
    )
