Implement MERGE-SORT() algorithm that reads from a file named "inputHW02.txt" a list of double numbers (max = 3,000,000 numbers), sorts those numbers and indicates time consumption. This programming question will address the advantage of using iteration loops over recursive calls as well as using INSERTION-SORT() as a procedure in MERGE- SORT(). Your program must perform the following actions: 1. Opens the given file name and reads all double numbers. For simplicity, we assume this file only contains numbers and nothing else. 2. Implements the function INSERTION-SORT() that only sort an array of maximum 25 numbers. The idea is that INSERTION-SORT() will be used as a sub-procedure to sort any sub-array when its size is small enough. 3. Four versions of MERGE-SORT() namely a.

Implement MERGE-SORT() algorithm that reads from a file named "inputHW02.txt" a list of double numbers (max :
3,000,000 numbers), sorts those numbers and indicates time consumption. This programming question will address the
advantage of using iteration loops over recursive calls as well as using INSERTION-SORT() as a procedure in MERGE-
SORT().
Your program must perform the following actions:
1. Opens the given file name and reads all double numbers. For simplicity, we assume this file only contains
numbers and nothing else.

INSERTION-SORT() will be used as a sub-procedure to sort any sub-array when its size is small enough.
