Defanging an IP Address
To solve this coding challenge, the goal is to transform a given valid IPv4 address into a 'defanged' version, where every period (.) is replaced with '[.]'. This can be easily achieved by splitting the input string at each period and then joining the resulting array of strings with the defanged period '[.]'.
Steps to Solve:
1. Split the IP Address:
Split the input IP address string at each period (.), which will create an array of strings, each representing an octet of the IP address.
2. Join with Defanged Period:
Join the array of octet strings using the defanged period '[.]' as the separator.
3. Return the Result:
The result of the join operation is the defanged IP address.
Pseudo Code:
FUNCTION defangIPaddr(address)
// Split the address at each period and join with "[.]"
RETURN address.SPLIT('.').JOIN("[.]")
END FUNCTION
Explanation:
Split:
The SPLIT('.') method divides the IP address into its constituent octets by using the period as a delimiter, resulting in an array of strings.
Join:
The JOIN('[.]') method then assembles these strings back into a single string, inserting '[.]' between each octet, effectively replacing each period in the original IP address.
This approach provides a simple and efficient way to create a defanged version of an IPv4 address.
