120. Triangle 给出一个三角形(数据数组),找出从上往下的最小路径和.每一步只能移动到下一行中的相邻结点上. 解法,自底向上 The idea is simple. Go from bottom to top. We start form the row above the bottom row [size()-2]. Each number add the smaller number of two numbers that below it. And finally we get…

Given an index k, return the kth row of the Pascal's triangle. For example, given k = 3,Return [1,3,3,1]. Note:Could you optimize your algorithm to use only O(k) extra space? 杨辉三角想必大家并不陌生,应该最早出现在初高中的数学中,其实就是二项式系数的一种写法. 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 1…

//此程序写出三个类,triangle,lader,circle:其中triangle类具有类型为double的a,b,c边以及周长,面积属性, //具有周长,面积以及修改三边的功能,还有判断能否构成三角形的boolean类. //lader类具有类型为double的上底下底和高,面积属性,具有返回面积的功能 //circlle 类具有类型为double的半径,周长和面积.具有返回周长面积的功能 //Lader类 class Lader { double shangDi; //上底 double…
