Webdetermine an optimal (i.e., one requiring the fewest comparisons) way to pair wise merge ‘n’ sorted files together. This type of merging is called as 2-way merge patterns. To merge an n-record file and an m-record file requires possibly n + m record moves, the obvious choice choice is, at each step merge the two smallest files together.
