Can you solve this real interview question? GCD Sort of an Array - You are given an integer array nums, and you can perform the following operation any number of times on nums: * Swap the positions of two elements nums[i] and nums[j] if gcd(nums[i], nu
在 LeetCode 中也有一道使用这个算法思想的题 [Kth Largest Element in an Array](http://www.cnblogs.com/grandyang/p/4539757.html)。快排的精髓在于选一个 pivot,然后将所有小于 pivot 的数字都放在左边,大于 pivot 的数字都放在右边,等于的话放哪边都行。但是此时左右两边的数组各自都不一定是有序的,需要...
