🧾 Lists

LinearList 🔗

Values are stored in an array of unique items. Fetch, add, and remove operations have O(n) time complexity.

SortedList 🔗

Values are stored in a sorted array of unique items. While add and remove operations have O(n) time complexity, the search operation has O(n log n) time complexity.

LinkedList 🔗

Each value is stored once using object references. Fetch, add, and remove operations have O(n) time complexity.

🏗️ Stacks

Stack 🔗

Last-in-first-out (LIFO) data structure. Items are stored in an array.

LinkedStack 🔗

Last-in-first-out (LIFO) data structure. Items are stored using object references.

🚶️️ Queues

Queue 🔗

First-in-first-out (FIFO) data structure. Items are stored in an array.

LinkedQueue 🔗

First-in-first-out (FIFO) data structure. Items are stored using object references.
