Values assigned with let and const are seen everywhere in JavaScript. It's become common to hear them explained like so: "const creates an constant (immutable) binding while bindings created with let can be changed (mutated) without issue." Alth…

There are some Common Bugs in C Programming. Most of the contents are directly from or modified from Prof. Liu Pangfeng's blog. Most credits should go to him. For all the following problems, answer the output message of the code, unless they are spec…
Ok, Go ahead. 1 (a) (b) (c) (d) 2 注:union 在 Common Lisp 中的作用就是求两个集合的并集.但是这有一个前提,即给的两个列表已经满足集合的属性了.具体的操作过程似乎是对第一个 list 中的每一个元素在第二个 list 中查找,如无则标记一下:待第一个 list 的所有元素在第二个 list 中查完以后将所有标记过的元素放入一个 list 中与第二个 list 进行合并.这意味着,如果刚开始给的两个 list 不完全满足集合的属性,则会有重复出现…
Given a binary tree, find the lowest common ancestor (LCA) of two given nodes in the tree. According to the definition of LCA on Wikipedia: “The lowest common ancestor is defined between two nodes v and w as the lowest node in T that has both v and w…
Given a binary search tree (BST), find the lowest common ancestor (LCA) of two given nodes in the BST. According to the definition of LCA on Wikipedia: “The lowest common ancestor is defined between two nodes v and w as the lowest node in T that has…
Write a function to find the longest common prefix string amongst an array of strings. 这道题让我们求一系列字符串的共同前缀,没有什么特别的技巧,无脑查找即可,我们定义两个变量i和j,其中i是遍历搜索字符串中的字符,j是遍历字符串集中的每个字符串.这里将单词上下排好,则相当于一个各行长度有可能不相等的二维数组,我们遍历顺序和一般的横向逐行遍历不同,而是采用纵向逐列遍历,在遍历的过程中,如果某一行没有了,说明其为…
题目简述: Write a function to find the longest common prefix string amongst an array of strings. 解题思路: class Solution: # @return a string def longestCommonPrefix(self, strs): if strs == []: return '' minl = 99999 for i in strs: if len(i) < minl: minl = l…
public class Solution { /** * @param strs: A list of strings * @return: The longest common prefix */ public String longestCommonPrefix(String[] strs) { // write your code here if(strs.length == 0){ return ""; } String prefix = strs[0]; int i =…
Given k strings, find the longest common prefix (LCP). Have you met this question in a real interview? Example For strings "ABCD", "ABEF" and "ACEF", the LCP is "A" For strings "ABCDEFG", "ABCEFG&…
