Combination Sum 组合求和 解题报告

1解题思想原题是说给定一些数字和一个目标值，从这些数字中挑选几个加起来，加起来后他的和正好等于目标值，其中一个数字可以选择多次。要求输出的不能有重复，并且组内的顺序是不能降序的。这道题首先必须要想到的就是排序了，排序是非常基本，又非常常用的一种操作。然后我们需要排除重复的（注意可以重复选择一个数，所以重复的最好先去掉，因为我们需要进行递归回溯，这样做可以降低无谓的开销）随后我们就开始求解，求解的做

Combination Sum | Java最短代码实现

原题链接：39.CombinationSum拓展博文：CombinationSumII|Java最短代码实现【思路】基本思路是先排好序，然后每次递归中把剩下的元素一一加到结果集合中，并且把目标减去加入的元素，然后把剩下元素（包括当前加入的元素）放到下一层递归中解决子问题。算法复杂度因为是NP问题，所以自然是指数量级的：publicList>combinationSum(int[]candidate

先转化出求Cnr中有多少奇数其实就是（n的二进制数中1的个数为k，则这个奇数为2^k)因为数很大，故要快速求出区间的奇数然后求0–low-1的奇数，0-high的奇数，相减既是结果求0–N中Cnr的奇数通过上图可以快速求出1----(2^N)-1的个数，其他数则可以用迭代的方式求出来（代码比赛写的有点残）#include#include#include#include#include#includ

Description给一个钟，N个刻度，再给T1,T2,T3个刻度，执行以下操作转2圈，再顺时针转到T1再转1圈，逆时针转到T2再顺时针转到T3问最多要转多少步？然后呵呵，这个只能钟转刻度不能转，所以说上面的都是逗你的，顺时针==逆时针，逆时针==顺时针Algorithm转到T1以后，后面的都是定的，所以只需要决定第一步最大步数就好了想都不要想就是T1旁边的那个，这样的话一个要转3*n-1，肯定
