🟩1108. 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.

string defangIPaddr(string address) 
    {
        string result;

        for(int i = 0;i < address.size();++i)
        {
            if(address[i]=='.')     // если встречаем точку, то прибавляем к ней []
            {
                result = result + "[.]";
            }
            else                    // иначе прибавляем просто встреченный символ
            {
                result = result + address[i];
            }
            

        }
        
        return result;

    }
