난이도 : Easy

 

풀이

class Solution:
    def reorderSpaces(self, text: str) -> str:
        spaces = text.count(' ')   # 빈칸 수
        words = text.split()  # 단어 분리
        wordsCnt = len(words)  # 단어 갯수
        
        rearrangeSpaces = 0 if wordsCnt == 1 else spaces//(wordsCnt- 1)  # 재정렬할 빈칸 수
        trailingSpaces = spaces - rearrangeSpaces * (wordsCnt - 1)  # 단어 끝에 올 빈칸 수
        
        return (' ' * rearrangeSpaces).join(words) + ' ' * trailingSpaces
