This paper presents an efficient algorithm for solving the Distinct Elements Problem, leveraging insights from Bar-Yossef et al. (2002). We explore the theoretical underpinnings of the algorithm, which addresses the challenge of identifying distinct elements within a given dataset, optimizing for both time and space complexity. By innovatively applying probabilistic techniques, our algorithm ensures a high accuracy rate when estimating unique elements while minimizing computational resources. This research contributes to the field of theoretical computer science and enhances algorithms used in data analysis.
