On a N * N grid, we place some 1 * 1 * 1 cubes that are axis-aligned with the x, y, and z axes. Each value v = grid[i][j] represents a tower of v cubes placed on top of grid cell (i, j). Now we view the projection of these cubes onto the xy, yz, and…

题目如下: 解题思路:分别求出所有立方体的个数,各行的最大值之和,各列的最大值之和.三者相加即为答案. 代码如下: class Solution(object): def projectionArea(self, grid): """ :type grid: List[List[int]] :rtype: int """ front = [0] * len(grid) side = [0] * len(grid) top = 0 for i in…
