Perform FizzBuzz on a stream of binary integers as fast as possible.

Input: 30 000 000 uint32 values in little-endian binary on STDIN (4 bytes each).

Output: For each number n, print one line:

FizzBuzz if n is divisible by both 3 and 5
Fizz if n is divisible by 3
Buzz if n is divisible by 5
n as a decimal string otherwise
