quicksort 的一般版本是 in-place 的 实际中,quicksort 的 O(nlgn) 常数项很小,所以比如 C 语言中常见常用 qsort Mergesort Mergesort 的伪码很容易在大名鼎鼎的 CLRS 上找到,最本质的要素就是拆分和合并为有序的array。代码看起来跟书上的伪码不太像,因为用了Python的一些语言特点,我觉得这是学算法很重要...

The two most prominent solutions for the sorting problem are Quicksort and Mergesort. While Quicksort is very fast on average, Mergesort additionally gives worst-case guarantees, but needs extra space for a linear number of elements. Worst-case efficient in-place sorting, however, remains a cha...
