CORE DEFINITION

Recursion, also translated as recursion, in mathematics and computer science, refers to a method where the definition of a function uses the function itself. The term recursion is also commonly used to describe the process of repeating things in a self-similar manner. For example, when two mirrors are approximately parallel to each other, the nested images in the mirrors appear as infinite recursion. It can also be understood as a process of self-replication.
