Python 3: Project-based Python, Algorithms, Data Structures - Complete merge sort algorithm and analyze updated executio

The video tutorial covers the process of adding and testing sorting functions, specifically Quicksort and Mergesort, in a Python script. It begins with importing and modifying the Quicksort function, followed by testing its functionality. The tutorial then demonstrates how to measure the execution time of the Quicksort function using Python's time module. After confirming Quicksort's performance, the video introduces the Mergesort function, detailing its implementation and testing. Finally, the tutorial identifies redundant code and plans to optimize it by creating functions.

What is the primary purpose of adding sorting functions to the demo file?

• To create a backup of the sorting functions

• To replace existing functions in the demo file

• To analyze and test the sorting functions

• To execute the functions directly from the demo file

Why was the import statement modified in the Quicksort function?

• To allow direct function calls without prefix

• To reduce the file size

• To add more print statements

• To improve the function's performance

What is the purpose of using the time module in the script?

• To convert time zones

• To synchronize system clocks

• To measure the execution time of functions

• To display the current date

How is the elapsed time calculated in the script?

• By dividing start time by end time

• By multiplying start and end times

• By subtracting start time from end time

• By adding start and end times

What was the observed time taken by the Quicksort algorithm to sort 10,000 integers?

• 0.08 seconds

• 0.02 seconds

• 0.2 seconds

• 0.8 seconds

What change was made to the Mergesort function before testing?

• Added print statements

• Renamed 'divideR' to 'mergesort'

• Removed all recursive calls

• Renamed the function to 'merge'

What is the next step planned after testing both sorting algorithms?

• Adding more sorting algorithms

• Refactoring the code to remove redundancy

• Removing the Mergesort function

• Increasing the list size for testing
