1108. Defanging an IP Address

Link: https://leetcode.com/problems/defanging-an-ip-address/

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"

Constraints:

• The given address is a valid IPv4 address.

class Solution {
public:
    string defangIPaddr(string address) {
        string output;
        for(auto ptr : address)
        {
            if(ptr!='.')
                output+=ptr;
            else
                output+="[.]";
        }
        return output;
    }
};
