2490. Circular Sentence

Approach

Split each word, then concatenate the sentence with itself (e.g., "abc""abcabc"). Check whether the last character of each word equals the first character of the next word (wrapping around).

Code

class Solution:
    def isCircularSentence(self, sentence: str) -> bool:
        sentence = sentence.split(' ')
        length = len(sentence)
        sentence += sentence
        for i in range(0, length):
            if sentence[i][-1] != sentence[i+1][0]:
                return False
        return True
