The basic idea is to first scan the list, find the middle point and break the list into two, sort two sub-lists recursively and merge them together. Obviously, time complexity would be O(nlogn). What is the space complexity? Since the function is called recursively and it uses stack spa...

Mergeksorted linked lists and return it as one sorted list. Analyze and describe its complexity. 题解: 是Merge Two Sorted Lists的进阶版,现在是k条,用divide and conquer, 两条两条合并 最后合并成一个大的。 Note: mergeSort中别忘了最后的返回值是lists[l]. 分析时间复杂度T(k) = 2T(k/2) +...

这样下一次只需合并3个链表,我们再合并1和3,最后和2合并就可以了。 总结 关于堆,理解的不是很透彻,可以参考以下两个文章继续学习:http://bubkoo.com/2014/01/14/sort-algorithm/heap-sort/https://github.com/qiwsir/algorithm/blob/master/heapq.md...
