TimSort is the default sorting algorithm in Python and Java, offering a hybrid approach combining insertion sort and merge sort for optimal performance.
The algorithm starts by calculating 'minimum runs' to determine the initial sorted subsequences efficiently.
TimSort uses insertion sort for small arrays and then switches to merge sort, optimizing the sorting process by leveraging the strengths of both algorithms.
The hybrid nature of TimSort provides stability, adaptability to partially sorted data, and guarantees O(n log n) worst-case performance, making it a versatile choice for various real-world data patterns.
