class Solution: def rotate(self, nums: List[int], k: int) -> None: n = len(nums) k = k % n # In case k is larger than n # Step 1: Reverse the entire array nums.reverse() # Step 2: Reverse the first k elements nums[:k] = reversed(nums[:k]) # Step 3: Reverse the remaining n-k elements nums[k:] = reversed(nums[k:]) ..

class Solution: def isPrefixOfWord(self, sentence: str, searchWord: str) -> int: words = sentence.split() for i, word in enumerate(words): if word.startwith(searchword): return i+1 return -1 Explanation:Split the Sentence: The input sentence is split into a list of words using .split(), which automatically handles single spaces.Iterate Over Words..
