In the merge sort algorithm, this subroutine is typically used to merge two sub-arrays A[lo..mid], A[mid+1..hi] of a single array A. This can be done by copying the sub-arrays into a temporary array, then applying the merge algorithm above. [1] The allocation of a temporary array can be avoided, but at the expense of speed and programming ease.
The problem can be solved by iteratively merging two of the k arrays using a 2-way merge until only a single array is left. If the arrays are merged in arbitrary order, then the resulting running time is only O(kn). This is suboptimal.
The sequential merge sort procedure can be described in two phases, the divide phase and the merge phase. The first consists of many recursive calls that repeatedly perform the same division process until the subsequences are trivially sorted (containing one or no element). An intuitive approach is the parallelization of those recursive calls. [19]
BlockSort(array) power_of_two = FloorPowerOfTwo(array.size) scale = array.size/power_of_two // 1.0 ≤ scale < 2.0 // insertion sort 16–31 items at a time for (merge = 0; merge < power_of_two; merge += 16) start = merge * scale end = start + 16 * scale InsertionSort(array, [start, end)) for (length = 16; length < power_of_two; length ...
To merge, Timsort copies the elements of the smaller array (X in this illustration) to temporary memory, then sorts and fills elements in final order into the combined space of X and Y. The original merge sort implementation is not in-place and it has a space overhead of N (data size).

Bitonic mergesort is a parallel algorithm for sorting. It is also used as a construction method for building a sorting network.The algorithm was devised by Ken Batcher.The resulting sorting networks consist of ( ()) comparators and have a delay of ( ()), where is the number of items to be sorted.

Overdoing it can give you the jitters, or even cause more serious health problems, but enjoying one or two cups a day—so long as you don't suffer from any of the conditions mentioned above—can ...
