Answer:

C. All Other Answers.

Explanation:

Worst case time complexity of quick sort is O(n²) if it selects always the smallest or the largest number in the array it can be optimized by always selecting the right pivot.Since quicksort is inplace it does not require additional memory to sort the array.Quick sort is considered better than merge sort in cases of arrays.

Mashcka [7]

Your issue is on line 19 in your if statement. In python, if you have more than one condition in an if statement, you have to explicitly mention it after the or.

Your if statement is

if again == "Y" or "y":

However, this will always return true because the second statement simply asks "y".

To correct this, simply change the if statement to:

if again == "Y" or again == "y":

This will correct your code.

Another thing to consider is to always convert a userinput (whenever possible) to one version, this can be accomplished in your code by converting "again" into one version by using the .lower function.

again = input("Would you like to draw a 3rd card? Y or N? ")

again = again.lower()

Hope this helps!
