Hi Guys can anyone help me with below code?

utility class that encrypts and decrypts names.

Your utility class should contain a cache of previously encrypted names so that if you encrypt or decrypt a name, the cache is checked first to see if the name is there. You can implement the cache any way you would like.

Encryption algorithm:

o Split the name into two equal parts. if it is an odd number length, then add a # at the

end of the name to make the length even. Example: Amin -> "Am" "in"

Example: Vimal -> "Vim" "al#"

o Reverse the parts and concatenate back into one string Example: Amin -> Am in -> inAm

Example: Vimal -> Vim al# -> al#Vim

o Decryption would reverse this algorithm and remove the '#' symbol if present.
