Definition: In the context of mathematics, a bijection is a function that is both one-to-one and onto. It means that each element in the domain can be paired with only one element in the range. In other words, for every input there corresponds exactly one output. For example: - The mapping from integers to their squares (x -> x^2) is a bijection. - The mapping from positive integers to their corresponding Fibonacci numbers (n -> f(n)) is also a bijection because
