8-Python-RondoForm Highest grade: Problem Statement Rondo Form is a type of musical structure, in which there is a recurring theme/refrain. Your job is to determine whether a given input is a valid Rondo Form or not. Here are the rules for valid Rondo forms: Rondo forms always start and end with an A section.

No letter should be skipped. There shouldn't be any repeats in the sequence (such as ABBACCA). Create a program which validates whether a given string is a valid Rondo Form.
