LeetCode 55. Jump Game 时间复杂度(O(n))

【LeetCode 55. Jump Game 时间复杂度(O(n))】 时间复杂度(O(n)),思想:动态规划

class Solution: def canJump(self, nums: [int]) -> bool: nums_len = len(nums) if nums[0] == 0 and nums_len > 1: return False path_status = [False] * nums_len path_status[0] = True path_index = 0 path_count = 1 for index, num in enumerate(nums): while path_index <= index + num: if path_index <= index: path_index = path_index + 1 if path_index >= nums_len: break path_status[path_index] = True path_index += 1 path_count += 1 return path_count == nums_len
