Could you please explain what "injective" means, and provide an example to illustrate the concept? I'm trying to grasp the concept but it's a bit abstract for me. Could you break it down into simpler terms? I'm particularly interested in understanding how injectivity applies in the realm of mathematics or cryptography, as I'm exploring its use in my current project. Would you mind guiding me through a real-world scenario or scenario related to my field of interest? Thank you in advance for your assistance.

An injective function, commonly known as a one-to-one function, is a mathematical concept that emphasizes uniqueness in its mapping. It ensures that each input corresponds to a unique output, without any overlap.

Numerous examples of injective functions can be found in our daily lives. One such instance is the correlation between a student's name and their roll number in a classroom setting. Each name corresponds exclusively to a single roll number, vice versa.

Another illustrative example is the relationship between a person and their shadow. In natural lighting conditions, each individual casts a unique shadow that cannot be replicated by another person. This uniqueness is akin to the one-to-one nature of an injective function.
