Mastering Python FizzBuzz: The Ultimate Interview Challenge Quiz

1. Understanding FizzBuzz Output

   If you run the standard FizzBuzz algorithm from 1 to 20, what will be printed in place of the number 15?

   1. A. Fizz
   2. B. Buzz
   3. C. FizzBuzz
   4. D. Fifteen
   5. E. FizzBuz

2. String Concatenation in FizzBuzz

   In Method 1, why is string concatenation used for building the FizzBuzz output, and what happens if num is 9?

   1. A. It always adds 'FizzBuzz', so 9 outputs 'FizzBuzz'.
   2. B. It appends both 'Fizz' and 'Buzz' for all numbers, so 9 outputs 'FizzBuzz'.
   3. C. It appends 'Fizz' or 'Buzz' based on divisibility; for 9, only 'Fizz' is added resulting in 'Fizz'.
   4. D. It skips string concatenation for all numbers, so 9 outputs '9'.
   5. E. It reverses the string before printing, so 9 outputs 'zziF'.

3. Conditional Logic Pitfalls

   Given the following code for FizzBuzz, which branch will execute when num = 10?nnif num % 3 == 0 and num % 5 == 0:n print('FizzBuzz')nelif num % 3 == 0:n print('Fizz')nelif num % 5 == 0:n print('Buzz')nelse:n print(num)n

   1. A. The first 'FizzBuzz' branch
   2. B. The second 'Fizz' branch
   3. C. The third 'Buzz' branch
   4. D. The else branch
   5. E. None; the code will error

4. FizzBuzz Range and Output Count

   How many times will the word 'FizzBuzz' appear when the basic FizzBuzz algorithm is run for numbers 1 through 20?

   1. A. 0
   2. B. 1
   3. C. 2
   4. D. 4
   5. E. 5

5. Common Errors in FizzBuzz

   What is a likely result if the order of the conditional statements in Method 2 is changed so that 'elif num % 3 == 0' comes before 'if num % 3 == 0 and num % 5 == 0'?

   1. A. 'FizzBuzz' will still be printed for multiples of both three and five.
   2. B. The program will not print anything for multiples of three and five.
   3. C. Multiples of three and five will only print 'Fizz'.
   4. D. Only 'Buzz' will be printed for any multiples of five.
   5. E. All outputs will be numbers only, never 'Fizz' or 'Buzz'.
