We introduce the recursive merge sort algorithm and compare it to insertion sort, which was discussed last lecture. We'll get to review while loops, and recursion as well. We'll continue analyzing the algorithms by counting the number of comparisons that are required. If you will take the next programming course (CS 2110) later, you will learn much more about the algorithms, different implementations, and analysis.
