Merge sort is arguably the first useful sorting algorithm you learn in computer science. Merge sort has a complexity of O(n log n), making it one of the more efficient sorting algorithms available. Additionally, merge sort is a stable sort (just like insertion sort) so that the relative or...

such as an array, would greatly increase the running time and complexity of the algorithm due to lengthy insertions and deletions. Strand sort is also useful for data which already has large amounts of sorted data, because
Halstead bases his approach on the mathematical relationships among the number of variables, the complexity of the code and the type of programming language statements. In this study, the 2 software complexity measures are applied to Merge sort algorithm. The intention is to study what kind of ...
According to the below Java code, in the function mergeSort, only two statements can create extra space. One is the centre, which requires the complexity of O(1) space. The other is the merge feature, which due to the presence of a temporary array(tem) requires O(n) space complexity....

This algorithm has O(n) best case Time Complexity and O(n log n) average and worst case Time Complexity. We achieve our goal using Recursive Partitioning combined with In Place merging to sort a given array. A comparison is made between this particular idea and other popular implementations....
