// Step 1: Run a loop from 1 to n, for reach iteration (i) perform the next steps
// Step 2: Declare a temporary empty string (inside loop, say output) 
// Step 3: If i is divisible by 3, append Fizz to the output.
// Step 4: If i is divisible by 5, append Buzz to the output.
// Step 5: If output is still an empty string, set it equal to i
// Step 6: Print output.
