leetcode 892. 三维形体的表面积(Surface Area of 3D Shapes) 目录 题目描述: 示例1: 示例2: 示例3: 示例4: 示例5: 解法: 题目描述: 在N * N 的网格上,我们放置一些 1 * 1 * 1 的立方体。 每个值 v = grid[i][j] 表示v 个正方体叠放在单元格 (i, j) 上。 返回结果形体的总表面积。
现在不仅仅是累加在一个小正方体上,而是在 nxn 的区间,累加出一个三维物体。由于之前做过那道三维物体投影的题 [Projection Area of 3D Shapes](https://www.cnblogs.com/grandyang/p/10865485.html),所以博主很思维定势的想到是不是也跟投影有关,然后又想当然的认为三维物体每一个面的面积就是该方向的投影,...

Surface Area of 3D Shapes The surface area of a solid is the sum of the areas of each face. When finding the surface area of 3D figures, consider it as unfolding the shape or flattening it out. Then find the area of each plane surface. The plane surfaces of a solid shape are basic...
