Witryna9 lut 2016 · That makes me guess that reversing descending runs is just a waste of time. I would seriously consider implementing 3 merge routines - merge two ascending runs, merge two descending runs, and merge ascending and descending runs (they would be almost identical, the only difference is in a run traversal direction). WitrynaRotate merge sort A rotate merge sort uses rotations to partition two sorted arrays until they're small enough to be merged using auxiliary memory. Blitsort does so by taking the center element of the first array, using a binary search to find all elements smaller than the center element in the second array, and performing an array rotation.
