Although the sorting algorithms discussed in class all used collection of numbers, any type of objects can also be sorted. For that to be possible, there should be a way to determine how 2 given objects should be compared. Java has an interface called Comparable that defines the following method: public int compareTo(Object other); compareTo should be overriden by the user-defined class in the following way:
a.compareTo(b) returns < 0 if a < b a.compareto(b) returns 0 if a = b a.compareTo(b) return > 0 if a > b
In this assignment you are asked to override compareTo in InstagramUser. Then adapt quick sort so it would work with an array of objects. Follow the TO-DOs in the given source code and submit InstagramUser class when you are done.
