@Spidey_guy check this question also https://gateoverflow.in/1467/gate1999-1-14-isro2015-42
here also they have mentioned to use 2-way merge sort so shouldn't we follow this method https://www.geeksforgeeks.org/merge-sort/ (first dividing and then merging!)

Another name for an iterative 2-way merge sort is bottom up merge sort, while another name for recursive merge sort is top down merge sort.
