Scala’s pattern matching is really really powerful. To taste its power I tried to implement a very basic but powerful sorting algorithm using Pattern matching. Basic merge sort algorithm includes two functions def mergeSort(seq: List[Int]): List[Int] → Which takes an unsorted collection and returns a sorted one. def merge(seq1: List[Int]…
