My dear friend Rahul was sad when nobody gave him anything important to do in URJA. So he decided to take out his anger by bringing down the URJA website. To do so he gathered some information about the IP address of the URJA website. 

The data he collected is in form of a string composed entirely of digit ('0'- '9'). Now to find a valid IP he has to check all possible IP that can be derived from the string.
A valid IP is an IP that has following property

It consist of 4 parts separated by three dots ('.').

Each part is a number in range (0 - 255).

Number in each part does not contain any leading zeros.
