# --description--
|
|
|
|
Given an array of sequential integers, with multiples of 3 and 5 replaced, determine if it's a valid FizzBuzz sequence.
|
|
|
|
In a valid FizzBuzz sequence:
|
|
|
|
- Multiples of 3 are replaced with "Fizz".
|
|
- Multiples of 5 are replaced with "Buzz".
|
|
- Multiples of both 3 and 5 are replaced with "FizzBuzz".
|
|
- All other numbers remain as integers.
|
|
|

`is_fizz_buzz([1, 2, "Fizz", 4, "Buzz"])` should return `True`.
