给定一维数组 original，将其转换为 m * n 的二维数组。若无法转换，则返回空数组。先检查数组长度 len(original) 是否等于目标二维数组大小 m * n，若不等则返回空数组。如长度相等，则按顺序将一维数组元素填充至二维数组中。时间复杂度为 O(m * n)，空间复杂度也为 O(m * n)。实现代码（P...
class Solution: def construct2DArray(self, original: List[int], m: int, n: int) -> List[List[int]]: # 如果长度不等于目标二维数组的大小,则直接返回空数组 if len(original) != m * n: return [] # 定义二维数组 ans: List[List[int]] = [[0] * n for _ in range(m)] # 初始化...
