Perfect Squares in Modular Arithmetic
A quadratic residue is a number that can be expressed as a perfect square under a specific modulus. Think of it as finding the 'square roots' of a number within a repeating cycle of integers. It is a foundational concept used to understand how numbers behave in modular arithmetic and plays a vital role in modern cryptography.
