Powersort

Powersort is an adaptive sorting algorithm designed to optimally exploit existing order in the input data with minimal overhead. Since version 3.11, Powersort is the default list-sorting algorithm in CPython and is also used in NumPy, PyPy, AssemblyScript, and Apple's WebKit. Powersort belongs to the family of merge sort algorithms. More specifically…
