1108. Defanging an IP Address
Easy
183503Share
Given a valid (IPv4) IP address, return a defanged version of that IP address.
A defanged IP address replaces every period "." with "[.]".
Example 1:
Input: address = "1.1.1.1"
Output: "1[.]1[.]1[.]1"
Example 2:
Input: address = "255.100.50.0"
Output: "255[.]100[.]50[.]0"
Java
class Solution {
public String defangIPaddr(String address) {
int len = address.length();
String res = "";
for(int i = 0; i<len; i++){
char add = address.charAt(i);
if(add == '.'){
res += "[.]";
} else {
res += add;
}
}
return res;
}
}
Python
class Solution:
def defangIPaddr(self, address: str) -> str:
res = ''
for add in address:
if add == '.':
res += '[.]'
else:
res += add
return res
