Скачать или смотреть LeetCode 1726 Tuple with Same Product Solution | HashMap Optimization in Java

Discover the optimal solution for LeetCode 1726 "Tuple with Same Product" using a HashMap to track product pairs efficiently. This approach avoids brute-force checks by storing pairwise product frequencies, achieving O(n²) time complexity. Learn how to count valid tuples (a, b, c, d) where a×b = c×d with all distinct elements. The solution includes step-by-step logic, edge case handling, and code implementations in Java. Perfect for coding interviews and algorithm optimization challenges.
