), and traversal. It explores ArrayList algorithms for insertion, deletion, and conversion between arrays and ArrayLists. Searching and sorting algorithms like linear/sequential search, selection sort, and insertion sort are discussed. Finally, it touches on ethical considerations related to data collection, emphasizing encryption, data minimization, security measures, and transparency.
