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。
Each valuev = grid[i][j]represents a tower ofvcubes placed on top of grid cell(i, j). Return the total surface area of the resulting shapes. 题目分析及思路 给定一个N*N网格,在其上放置1*1*1的小方块,二维数组的值即为当前位置的高度,要求返回这样一个3D图形的表面积。可以遍历数组的每一个...

Now that we have the dimensions of each side, we can find out the area of each 2-dimensional shape that we had obtained in the first step. After fining the area of all the 2-dimensional shapes, the last step is to add up all the area to get the total area which is the surface ...
