题目要求 You have a list of points in the plane. Return the area of the largest triangle that can be formed by any 3 of the points. 题目分析及思路 给定一个平面上的一组点,要求得到由这些点中任意三个所能组成最大面积的三角形.可以对这一组点进行三三组合,然后利用已知三点求三角形面积的公式得到每一组点所对应的三角形面积,最后取其中的最大值即为所求. python代码 class…

给定包含多个点的集合,从其中取三个点组成三角形,返回能组成的最大三角形的面积. 示例: 输入: points = [[0,0],[0,1],[1,0],[0,2],[2,0]] 输出: 2 解释: 这五个点如下图所示.组成的橙色三角形是最大的,面积为2. 注意: 3 <= points.length <= 50. 不存在重复的点. -50 <= points[i][j] <= 50. 结果误差值在 10^-6 以内都认为是正确答案. class Solution { public:…
题目描述 给定一个非负整数 numRows,生成杨辉三角的前 numRows 行. 在杨辉三角中,每个数是它左上方和右上方的数的和. 示例: 输入: 5 输出: [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ] 思路 对任意的n>0有 f(1, n)=1,(n>0) f(1, 2)=1,(n=2) f(i,j) = f(i-1, j-1)+f(i, j-1),i>2,j>2 代码实现 package Array; import java…
