468. 验证IP地址 编写一个函数来验证输入的字符串是否是有效的 IPv4 或 IPv6 地址. IPv4 地址由十进制数和点来表示,每个地址包含4个十进制数,其范围为 0 - 255, 用(".")分割.比如,172.16.254.1: 同时,IPv4 地址内的数不会以 0 开头.比如,地址 172.16.254.01 是不合法的. IPv6 地址由8组16进制的数字来表示,每组表示 16 比特.这些组数字通过 (":")分割.比如, 2001:0db8:85a…

题目标签:String 题目给了我们一组 ip address,让我们把 . 变成 [.],这题可以用replace,但是这样做的话,好像没意义了.所以还是走一下array,具体看code. Java Solution: Runtime:  0 ms, faster than 100 % Memory Usage: 34 MB, less than 100 % 完成日期:08/01/2019 关键点:n/a class Solution { public String defangIPaddr(…
93. Restore IP Addresses Given a string containing only digits, restore it by returning all possible valid IP address combinations. For example: Given "25525511135", return ["255.255.11.135", "255.255.111.35"]. (Order does no…
