14. Merge Sort: Analysis

The chapter focuses on the divide and conquer strategy as exemplified by the merge sort algorithm, emphasizing its efficiency compared to traditional sorting methods such as insertion and selection sort. It explains how merge sort operates by recursively splitting and merging lists while analyzing the time complexity, demonstrating its optimal performance of O(n log n). Although merge sort offers significant improvement in speed for large datasets, it does come with drawbacks, including the requirement for additional memory and a recursive approach that can be less efficient in practice.
