Question
make the array an arraylist instead and include the file you used
![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. MERGE-SORT-A(): Using recursive calls and NO INSERTION-SORT() as a sub-procedure
b. MERGE-SORT-B(): Using ITERATIVE loops (i.e, NO recursion) and NO INSERTION-SORT() as a sub-
procedure.
MERGE-SORT-C(): Using recursive calls and INSERTION-SORT() as a sub-procedure.
d. MERGE-SORT-D(): Using ITERATIVE loops (i.e, NO recursion) and INSERTION-SORT() as a sub-
procedure.
4. For testing purpose, write another procedure to randomly generate N numbers and write them to a given file
name filename where N and filename are input parameters.
Report your MERGE-SORT() time consumption on the following input sizes: N = 1M, 1.5M, 2M, 2.5M and
3M numbers. That is, for each input size N, calls step 4 to generate N numbers and write them to the given file
name (e.g., “inputHW02.txt"). Then reads from that file and performs MERGE-SORT-A(), MERGE-SORT-B(),
MERGE-SORT-C(), MERGE-SORT-D) and report each of their time consumptions in a graph.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7c0e66d0-00ad-421a-b122-ab7641acfa57%2Fd5288130-b7b4-45d4-a4d6-7f00776c0014%2F12a1mjk_processed.png&w=3840&q=75)
