Merge sort to insertion sort when fewer than seven array elements are being sorted. The Linux kernel uses merge sort for its linked lists. Python uses Timsort, another tuned hybrid of merge sort and insertion sort, that has become the standard sort algorithm in Java SE 7 (for arrays of non-primitive types), on the Android platform, and in GNU Octave. Merge sort In computer science, merge sort (also commonly spelled mergesort) is an efficient, general-purpose, comparison-based sorting algorithm. Most implementations produce a stable sort, which means that the order of equal elements is the same in the input and output. Merge sort
