Suggested Applications:

• Small Data: For datasets around 1,000 elements, Native Arrays, Queues, and Stacks provide excellent performance.
• Medium Data: Up to 10,000 elements, use AVL Tree for balanced tree operations and Min/Max Heap for priority-based insert/extract operations.
• Large Data: At 100,000 elements, consider using B-Trees or Red-Black Trees for optimized insertion and search performance.
• Extra Large Data: Beyond 1,000,000 elements, B-Trees, with their balanced and efficient nature, are superior for handling large datasets, especially for search and delete operations.

Sorting Algorithms:

• Heap Sort: Ideal for priority queues and constrained memory environments.
• Merge Sort: Best for linked lists and large datasets on disk where stable sorting is needed.
• Tim Sort: Great for real-time systems and partially sorted data, widely used in production environments.
• Native Sort: Versatile for general-purpose sorting with built-in optimization.

Searching Algorithms:

• Binary Search: Perfect for quick lookups in large, sorted datasets (e.g., databases).
• Exponential Search: Useful for unbounded or sparse datasets to find a starting range for binary search.
• Hybrid Search: Adapts well to changing dataset sizes, ideal for large applications and databases.
• Linear Search: Suited for small, unsorted datasets where search is infrequent.
• Ternary Search: Good for distinct, ordered data ranges, often in optimization or game algorithms.

binarySearch(sortedData, target, { compareFn: (a, b) => a - b, isSorted: true });
ternarySearch(data, target, 0, sortedData.length - 1, {
        compareFn: (a, b) => a - b,
        isSorted: false,
    });

const queue = new Queue<number>();
data.forEach((item) => queue.enqueue(item));

const avlTree = new AVLTree<number>();
avlTree.insert(10);
avlTree.insert(20);
avlTree.insert(5);
avlTree.insert(4);
avlTree.insert(15);
avlTree.search(10);
