WebSimple Merge Sort Program in C++ Definition Merge sort is an O (n log n) comparison-based sorting algorithm. Most implementations produce a stable sort, which means that the implementation preserves the input order of equal elements in the sorted output.
WebBackground. Merge sort belongs to the group of "divide and conquer" algorithms. It is very efficient (runs in O (n * log 2 n)) and makes low number of comparisons. One disadvantage is the amount of extra space that it requires. Normally this sorting is stable, meaning that it preserves the order of equal elements. WebAug 19, 2012 · Actually, the advantage of merge sort is that it doesn't need arrays in the first place. In fact, merge sort can be implemented in-place, using sequences with rather low requirements (I'd think you can implement it on forward iterators).

WebMerge sort is based on Divide and conquer method. It takes the list to be sorted and divide it in half to create two unsorted lists. The two unsorted lists are then sorted and merged to get a sorted list. The two unsorted lists are sorted by continually calling the merge-sort algorithm; we eventually get a list of size 1 which is already sorted.
