Fizz Buzz

Question

Write a program that outputs the string representation of numbers from 1 to n.

But for multiples of three it should output “Fizz” instead of the number and for the multiples of five output “Buzz”. For numbers which are multiples of both three and five output “FizzBuzz”.

Example:

n = 15,

Return:
[
    "1",
    "2",
    "Fizz",
    "4",
    "Buzz",
    "Fizz",
    "7",
    "8",
    "Fizz",
    "Buzz",
    "11",
    "Fizz",
    "13",
    "14",
    "FizzBuzz"
]

Thought

The implementation is below and the algorithm is straightforward.

Code

class Solution(object):
    def fizzBuzz(self, n):
        """
        :type n: int
        :rtype: List[str]
        """
        ans = []
        for i in xrange(1, n + 1):
            item = ''
            if i % 3 == 0:
                item += 'Fizz'
            if i % 5 == 0:
                item += 'Buzz'
            if item == '':
                item = str(i)
            ans.append(item)
        return ans
