def str2bin(s): temp = s.split('.') result = '' for i in range(len(temp)): temp[i] = str(bin(int(temp[i]))[2:]) if len(temp[i]) < 8: temp[i] = '0'*(8-len(temp[i])) + tenp[i] result += str(temp[i]) return result
问题描述: 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 not matter) 算法分析: 首先我们
下面代码是关于Java将ip字符串转换成整数的代码,希望对各位有较大用途. public class IpUtil { public static int Ip2Int(String strIp){ String[] ss = strIp.split("\."); if(ss.length != 4){ return 0; } byte[] bytes = new byte[ss.length]; for(int i = 0; i < bytes.length; i++){ by
今天鹅厂店面,最后问了一个ip地址字符串和整数间无损转化的问题,晚上有时间了手撸了一下代码. public class IPstr { public static void main(String args[]){ ipstrToint sti=new ipstrToint(); int ip=0; ip=sti.strToint("127.11.22.33"); if(ip==0) System.out.println("无效IP"); else System.o
