Merge sort is one of the most powerful sorting algorithms. Merge sort is widely used in various applications as well. The best part about these algorithms is that they are able to sort a given data in O(nlogn) complexity as against O(n2) complexity (we will soon see how) of bubble sort and selection sort. Moreover, merge sort is of interest because it creates an excellent case study for one of the widely used techniques in Computer Science – divide and conquer.
A famous person once said: The most important skill to learn in today’s world is to know how to write a computer program. Today, computers have entered in almost all industries. Be it the autopilot in an aircraft or digital speedometer in your bike, computers in various forms surround us. Computers are extremely useful for an organization to scale up well. Gone are the days of pen and paper. Today, in order to store and access your information, you absolutely need computers.
