Special Palindrome String

You are given a string s. Your task is to determine whether it is possible to rearrange the characters of s such that it forms a special string. A special string is defined as a palindrome that contains at least three unique characters.

A palindrome is a string that reads the same forwards and backwards. However, even if a palindrome can be formed from the characters of s, the additional condition of having at least three distinct characters must be met.

If both conditions are satisfied, print "It's special!"; otherwise, print "Sorry, try again!".

Note: Reordering of characters is allowed.
