[challenge] Decrypt "º¥ÒÒíḆçBí±¥Ø" to display greeting.

Question

The program
https://code.sololearn.com/ca3ejoGCXizb
takes a formula like
x + 3
or
(x -3) * 2
as Input.
If you enter x + 3, the decryption will for example do this mapping:
a -> d
A -> D
r -> u
... three characters forward you see.
Find a forrmula, that will decrypt the string above into a greeting.
Use your own weapon, it is no need to use Python. The prog is just to test the result.
Have fun!
