Java Sorting Algorithms: Merge Sort
Today we are going to analyze one of the most used sorting algorithms: the Merge Sort. It is part of the Divide and Conquer family, just like the Quick Sort. Merge Sort offers a better performance despite of the Quick Sort since its complexity remains O(n log n) keeping performances. It is also called "algorithm by fusion" The main defect of the Merge…
