11. Uniqueness Proof of the CRT

The discussion focuses on the uniqueness proof of the Chinese Remainder Theorem (CRT) and highlights important properties such as Euclid's Lemma and basic properties of divisibility. Emphasizing the proof strategy involves demonstrating that if two numbers yield the same results under a set of linear congruences, they must be identical within a specified range. Real-world applications of the CRT, particularly in cryptography and arithmetic with large values, are emphasized, showcasing its practical significance.
