----------HackerRank
- Task
- You are given a partial code that is used for generating the HackerRank Logo of variable thickness.
- Your task is to replace the blank (__) with rjust, ljust or center.
- Input Format
- A single line containing the thickness value for the logo.
- Constraints
- The thickness must be an odd number.
- 0 < thickness <= 50
- Output Format
- Output the desired logo.
문제풀이
- .ljust(width), .center(width) .rjust(width)를 이용하여 ____를 알맞은 함수로 변경하는 문제
- 처음엔 무슨소리가 싶긴했는데, 해당 문제의 output을 잘보며 center, ljust, rjust를 잘 이용하여 풀면 쉬웠다.
