[MCW-01] | Mykyta Kalachuk | Necessary fixes to complete module control work task

[new-user888]

Task

Variant Assignment

Variant: 9 (for student Mykyta Kalachuk)

Variant Calculations

• C3 = 9 % 3 = 0 → Doubly-linked list
• C5 = 9 % 5 = 4 → Hexadecimal (base-16) primary system
• C7 = 9 % 13 = 9 → Convert to Binary (base-2) secondary system
• Additional Operation (variant 9): Multiply list by constant = 9

What to do

Core Implementation

Node Structure

• Inner class: Node
• Fields:
  • byte data - stores the digit value
  • Node next - pointer to next node
  • Node prev - pointer to previous node
• Type: Doubly-linked, linear (not circular)

Class Fields

• Node head - first node in the list
• Node tail - last node in the list
• int size - number of elements
• int radix - current number system (16 or 2)

Updated Makefile (To make "Make" be working on windows host)
