--description--

Given an integer (n), return an array of integers from 1 to n (inclusive), replacing numbers that are multiple of:

  • 3 with "Fizz".
  • 5 with "Buzz".
  • 3 and 5 with "FizzBuzz".

--hints--

fizz_buzz(2) should return [1, 2].

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(fizz_buzz(2), [1, 2])`)
}})

fizz_buzz(4) should return [1, 2, "Fizz", 4].

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(fizz_buzz(4), [1, 2, "Fizz", 4])`)
}})

fizz_buzz(8) should return [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8].

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(fizz_buzz(8), [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8])`)
}})

fizz_buzz(20) should return [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8, "Fizz", "Buzz", 11, "Fizz", 13, 14, "FizzBuzz", 16, 17, "Fizz", 19, "Buzz"].

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(fizz_buzz(20), [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8, "Fizz", "Buzz", 11, "Fizz", 13, 14, "FizzBuzz", 16, 17, "Fizz", 19, "Buzz"])`)
}})

fizz_buzz(50) should return [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8, "Fizz", "Buzz", 11, "Fizz", 13, 14, "FizzBuzz", 16, 17, "Fizz", 19, "Buzz", "Fizz", 22, 23, "Fizz", "Buzz", 26, "Fizz", 28, 29, "FizzBuzz", 31, 32, "Fizz", 34, "Buzz", "Fizz", 37, 38, "Fizz", "Buzz", 41, "Fizz", 43, 44, "FizzBuzz", 46, 47, "Fizz", 49, "Buzz"].

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(fizz_buzz(50), [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8, "Fizz", "Buzz", 11, "Fizz", 13, 14, "FizzBuzz", 16, 17, "Fizz", 19, "Buzz", "Fizz", 22, 23, "Fizz", "Buzz", 26, "Fizz", 28, 29, "FizzBuzz", 31, 32, "Fizz", 34, "Buzz", "Fizz", 37, 38, "Fizz", "Buzz", 41, "Fizz", 43, 44, "FizzBuzz", 46, 47, "Fizz", 49, "Buzz"])`)
