Round 1 Q1 Given a log file with list of tuples(TIMESTAMP, USER, PAGE_TYPE) where page type being the page visited. Form sequence of pages the user had visited and then find the most common sequence. The question was later changed to form triplets of sequences. e.g if the sequence is A->B->C->D->E->F, the triplet sequences would be A B C B C D D E F and then find the most common sequence.
1. Class A has variable a, Class B extends from A which has b, Class C extends from Class B which has c. Set values for those variables. Write a clone method which returns a deep copy. For example ClassA a = new ClassC(5); which will print 5,4,3 set by constructors in those classes. ClassA x = a.myClone(); x.print() should also print 5,4,3.
