problem 892. Surface Area of 3D Shapes 题意:感觉不清楚立方体是如何堆积的,所以也不清楚立方体之间是如何combine的.. Essentially, compute the surface area of each grid but substract the overlapping areas. All areas = surface + combined area so we have surface = * total_count - * combi…
On a N * N grid, we place some 1 * 1 * 1 cubes. Each value v = grid[i][j] represents a tower of v cubes placed on top of grid cell (i, j). Return the total surface area of the resulting shapes. Example 1: Input: [[2]] Output: 10 Example 2: Input: [[1…

题目如下: 解题思路:对于v = grid[i][j],其表面积为s = 2 + v*4 .接下来只要在判断其相邻四个方向有没有放置立方体,有的话减去重合的面积即可. 代码如下: class Solution(object): def surfaceArea(self, grid): """ :type grid: List[List[int]] :rtype: int """ res = 0 for i in range(len(grid)):…
