This approach iterates through numbers from 1 to n and applies conditional logic using modulus operations to determine if a number should be represented as "Fizz", "Buzz", or "FizzBuzz". If none of these conditions are met, the number itself is returned as a string.
Time Complexity: O(n) as we iterate through each number from 1 to n once.
Space Complexity: O(n) for the output array.

22The function fizzBuzz takes an integer n and generates an array of strings. It checks each number from 1 to n for divisibility by 3 and 5. The use of strdup efficiently allocates memory for the strings returned.
This approach uses a hash map to store possible outputs, simplifying conditional checks. By mapping integers to their respective Fizz or Buzz values, we consolidate decision logic, reducing redundancy in the code.
Time Complexity: O(n), since each element is evaluated once.
Space Complexity: O(n) due to storage for result strings.
1varThe JavaScript variation leverages a constant array to encapsulate decisions for values, reducing verbosity in branching and improving code simplicity.
