LeeCode是一个有意思的编程网站,主要考察程序员的算法 第二题: You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked l…
问题 给出两个非空的链表用来表示两个非负的整数.其中,它们各自的位数是按照逆序的方式存储的,并且它们的每个节点只能存储一位数字. 如果,我们将这两个数相加起来,则会返回一个新的链表来表示它们的和. 您可以假设除了数字 0 之外,这两个数都不会以 0开头. Give two non-empty linked lists to represent two non-negative integers. Among them, their respective digits are stored in…

193. Valid Phone Numbers Given a text file file.txt that contains list of phone numbers (one per line), write a one liner bash script to print all valid phone numbers. You may assume that a valid phone number must appear in one of the following two f…
Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. Example: Input: "babad" Output: "bab" Note: "aba" is also a valid answer. Input: "cbbd" Output: &qu…
