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…
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…
Given a start IP address ip and a number of ips we need to cover n, return a representation of the range as a list (of smallest possible length) of CIDR blocks. A CIDR block is a string consisting of an IP, followed by a slash, and then the prefix le…
