1a.Write a method to generate 3 randomly generated arrays of integers with the size of 10,000 100,000 and 1,000,000. Make sure each randomly generated number in the lists is a 7-digit number.

1b. Populate the MasterClass.py file by implementing sorting algorithms in their respective methods.

1c. Feed the randomly generated arrays into each method by calling them from your own program and record the time it takes for each sorting algorithm.

This is the picture of the masterclass;

class masterclass: def quickSort (arr): return arr def selectionsort (arr) : return arp def mergeSort (arr): return arr
