412. Fizz Buzz

1. Description

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”.

2. Example

Example 1:
n = 15,
Return:
[
“1”,
“2”,
“Fizz”,
“4”,
“Buzz”,
“Fizz”,
“7”,
“8”,
“Fizz”,
“Buzz”,
“11”,
“Fizz”,
“13”,
“14”,
“FizzBuzz”
]

3. Solutions

My Accepted Solution

n = number
Time complexity: O(n)
Space complexity: O(n)

class Solution 
{
public:
    // vector<string> fizzBuzz(int n)
    vector<string> fizzBuzz(int number) 
    {
        vector<string> result;
        
        for(int i = 1; i <= number; i++)
        {
            if(i % 3 == 0 && i % 5 == 0)
                result.push_back("FizzBuzz");
            else if(i % 3 == 0)
                result.push_back("Fizz");
            else if(i % 5 == 0)
                result.push_back("Buzz");
            else
                result.push_back(to_string(i));
        }
        
        return result;
    }
};
