A **bijection** is a type of function in mathematics that establishes a one-to-one correspondence between elements of two sets. A function \\( f: A \\to B \\) is called a bijection if it satisfies two main properties: 1. **Injective (One-to-One):** For every pair of distinct elements \\( a_1, a_2 \\in A \\), \\( f(a_1) \\neq f(a_2) \\).
