Merge sort

Merge Sort recursively sorts a given collection of numbers or elements by using the divide and conquer strategy in less time. It is one of the most used algorithms, with the worst-case time complexity of O (n log n). It was invented by John Von Neumann. The algorithm continuously divides an array into sub-arrays until each sub-array consists of a single element. It then merges those sub-arrays to produce a sorted array.

I REALLY NEED HELP!!!!! We learnt this week that lists can be multi-dimensional. For e.g., the following is another example of 2-D multidimensional list. Each row contains student name followed by their grades in 5 subjects: students = [ ['Anna', 98.5, 77.5, 89, 93.5, 85.5], ['Bob', 77, 66.5, 54, 90, 85.5], ['Sam', 98, 97, 89.5, 92.5, 96.5] ] To access, a specific row, you would use students[row_number][column_number]. students[0][0] would print 'Anna' students[0][1] would print 98.5 Write a program that defines a function that takes a list as an argument, adds the scores of each student, calculate average for each student (append them to a separate list) and display them. Your program should: Define a function display_average(students) that takes in a 2-D list as an argument. Display the original list using for/while loop. Calculate and display the average of each student. You do not need to ask user for input. You can use your own 2-D lists with at-least 2-rows.
Implement a function countMultiples in Python that: accepts a single argument, a 2-dimensional list (e.g, list of lists) containing non-negative integers, and returns the count of those integers that are multiples of 5 but that are not not multiples of 10.
