Optimal merge pattern algorithm

WebMar 19, 2024 · When two or more sorted files are to be merged altogether to form a single file, the minimum computations are done to reach this file are known as Optimal Merge Pattern. If more than 2 files need to be merged then it can be done in pairs. For example, … WebSep 7, 2024 · Answer: (A) Explanation: Using optimal merge pattern algorithm arrange files in increasing order of records: D A C B E 5 10 15 20 25. Now, minimum number of record movements required = sum of internal node’s value = 15 + 30 + 45 + 75 = 165. So, option (A) is correct. Quiz of this Question.
