Merge k sorted
linked lists and return it as one sorted list. Analyze and describe its complexity.
解题思路:一般而言，合并两个有序链表较为简单，只需要两两逐个比较即可.而本题要求合并K个有序链表，事实上只需要对每个链表的头结点建堆.每次输出最小值.并插入其所在链表的下个结点并维护堆.可以利用S...

There are two sorted arrays A and B of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)).
用二分的方法求合并数组的中值。用找第k大的值来求，不断去掉较小的一半，...

Given a string S and a string T, find the minimum window in S which will contain all the characters in T in complexity O(n).
For example,
S = "ADOBECODEBANC"
T = "ABC"
Minimum window is...
Given an integer n, return the number of trailing zeroes in n!.
Note: Your solution should be in logarithmic time complexity.
题目是非常简单的，计算一个数字递归相乘后末尾0的个数
在相乘出现2*5才有可能出现0,2一般是足够的，主要是5的个数，因为是阶乘，...
