Merge Sort is a kind of Divide and Conquer algorithm in computer programming. In this tutorial, you will understand the working of merge sort with working code in C, C++, Java, and Python.
(nlogn)worst-case running time, which happens to be one of the best among the contemporary general-purpose sorting algorithms. It has the linear space complexity in a worst-case scenario that is more thanthe quick sort algorithmoffers. The latter one tends to be relatively faster in practice...

Especially since you never check for infinity. Also because you always know the exect bounds and should not fall off the end. Also this is a particularly bad implementation of the algorithm. Most version I have seen use a split/merge in place algorithm. Thus you don't need to copy data ...
The mergesort algorithm is stable. The qsort and qsort_r functions are an implementation of C.A.R. Hoare's "quicksort" algorithm, a variant of partition-exchange sorting; in particular, see D.E. Knuth's "Algorithm Q". Quicksort takes average time. This implementation uses median ...
