Perhaps the easiest way is to modify the standard merge sort so that it uses non … WebThe sort ends with a single k -way merge, rather than a series of two-way merge passes as in a typical in-memory merge sort. This is because each merge pass reads and writes every value from and to disk, so reducing the number of passes more than compensates for the additional cost of a k -way merge. goldfish salt treatment
