mathematical function that preserves distinctness
AI overview
An injection is a type of mathematical function where each input produces a unique output—no two different inputs map to the same output. This matters because injections are fundamental building blocks in mathematics that help us understand how sets relate to each other and whether information is preserved without loss when transforming data from one form to another.
