My current code seems to work even with duplicated keys but I think if all the keys are the same, I will get a O(n^2) complexity (partitioned arrays will be very unbalanced).CanHow canIslightlyupdatemy current code to address this issue? Thanks Python Quicksort Implementation with duplicat...
【Python&Sort】QuickSort Python版的快排,使用递归。 1.设置递归终止条件,当元素个数<1时 2.从列表中pop出一个元素pv 3.列表中的剩余值与pv进行对比,大的放入smaller列表,小的放入larger列表 4.返回qs(smaller)+[pv]+qs(larger) 代码如下: 1defquicksort(array):2smaller=[];larger=[]3iflen(array)<1...

I cooked up this function after finding the wonderful Haskell quicksort (which I’ve reproduced above) athttp://www.haskell.org/aboutHaskell.html. After marveling at the elegance of this code for a while, I realized that list comprehensions made the same thing possible in Python. Not for ...
