本文介绍了一个简单但实用的问题——在一个所有元素几乎都成对出现的数组中找到那个唯一的单例元素。这是一个经典的编程面试题，通过对位操作的巧妙运用实现了高效解决。

题目大意：一个整数数组，每个元素都出现了2次，只有一个元素出现了一次；find it.

基本思路：一道easy题，且通过率超过50%，但是没有想出来....尴尬...

code:

int singleNumber(int* nums, int numsSize) {
    int i=0;
    int res=0;
    while(i

题目大意：给定一个单链表，找出其环路的起始点。若不存在环路，则返回NULL。 大概思路：数学题 头结点是A，题目要求的环路起点为B，在141题快慢指针算法中求出的相遇点为C。 设A到B的距离为a,B到C的距离为b，环路一圈的距离为c。 则(a+b)*2=a+b+k*c;(其中k为常数) 则a+b=k*c; 两个指针分别以相同速度从A、B出发，第一个指针到达B点，路程为a，第二个指针此时

难度：Medium 题目大意：给出一个整数n（n>=2)，可以分解为多个正整数相加（至少2个），求各种组合中，乘积的最大值。 思路：若a为其中一个分解因子，1 若a>=5,则a可以分解为3*（a-3）=3*a-9>a; 若a=4,可以分解为2*2=4； 即n尽可能的分解为3和2。 又因为3*3>2*2*2,所以，可以先分解出尽可能多的3。 再根据n模3的结果来做判断即可。 具体可以

思路一：先二叉排序，然后，循环一遍比较相邻的数，相等返回True，没有重复的则返回False。时间复杂度为O(nlogn). 结果：测试用例（1、2、3、4....29999）超时。 思路二：以空间换时间，采用时间复杂度为O(n)的桶排序，替换二叉排序。 结果：因为桶排序只考虑了数组为正整数的情况，测试用例[1,5,-2,-4,0]出错。 思路三：改写桶排序，将范围从正整数调整为-3000
