Homework Answers
Merge sort is a type of method that is depending upon the divide and conquer approach where the concept of splitting a lists as many sublists having a one element and merge them employing the merge( ) the sublists in a way outputs as a sorted list.It is a famous sorting approach ,a huge manner for evolve the belief in constructing recursive approaches, So duration taken for this sort is not so much.Divide-and -conquer contains three phases as below.
Divide - split into several little sublists.
conquer - Recursively sort the every two sublists nearly n/2 lists ,consuming few amount of duration.
combine - unite the solutions of sublists for detecting the solution of real lists.

The steps in divide-and-conquer approach are: A) Divide an instance of a problem into one or more smaller instances. B) Use recursion until the instances are sufficiently small. C) Conquer (solve) these small and manageable instances. D) Combine the solutions to obtain the solution of the original instance. Select one: True False

Suppose that, in a divide-and-conquer algorithm, we always divide an instance of size n of a problem into n subinstances of size n/3, and the dividing and combining steps take linear time. Write a recurrence equation for the running time T(n), and solve this recurrence equation for T(n). Show your solution in order notation. please help solve this..
