问题: Given an array S of n integers, are there elements a, b, c in S such that a + b + c = 0?Find all unique triplets in the array which gives the sum of zero.Note: The solution set must not contain duplicate triplets.For example, given array S = [-1,…

问题: Given an array S of n integers, find three integers in S such that the sum is closest to a given number, target.Return the sum of the three integers. You may assume that each input would have exactly one solution.For example, given array S = {-1…

一.题目描写叙述 二.解题技巧 该题与3Sum的要求类似.不同的是要求选出的组合的和与目标值target最接近而不一定相等.但实际上,与3Sum的算法流程思路类似,先是进行排序.然后顺序选择数组A中的下标为i的元素值作为组合中三个数的最小值,进而寻找另外两个更大的值,最后求出三个数的和.只是的地方在于这里是寻找最靠近给定值.寻找最靠近的值就无全部反复的事情了,所以能够不考虑夹逼的过程中的越过同样元素的过程,尽管越过同样的元素速度会快一些,可是代码长度也会加长. 这道题难的地方可能在于刚開始这样的…

[Python练习题 015] 一球从100米高度自由落下,每次落地后反跳回原高度的一半,再落下.求它在第10次落地时,共经过多少米?第10次反弹多高? ---------------------------------------------------------- 这题其实都可以笔算出来,因为也就是落地10次.看网上给出的结果也是五花八门,也不知道自己算的对不对,请大神们赐教. 我的思路是:除了第1次从100米高度落下,其余的9次都经历了"反弹-落地"的过程,每个过程来回走过的长…
