Single Number
Given an array of integers, every element appears twice except for one. Find that single one.
Note:
Your algorithm should have a linear runtime complexity. Could you implement it ...

Sort a linked list in O(n log n)
time using constant space complexity.
分析:排序算法中,堆排序、归并排序、快速排序、希尔排序的时间复杂度是nlogn,堆排序和归并排序对下标依赖性比较强,比较适合顺序表的排序,对链表处理起来比较复杂。希尔排序用的比较少。所以我选择的是快速排序,结果是正确的,但时间超出限...
