Recursion is a way of programming or coding a problem, in which a function calls itself one or more times in its body. Usually, it is returning the return value of this function call. If a function definition fulfils the condition of recursion, we call this function a recursive function.
A recursive definition, sometimes also called an inductive definition, is one that defines a word in terms of itself, so to speak, albeit in a useful way. Normally this consists of three steps: 1  At least one thing is stated to be a member of the set being defined; this is sometimes called a base set. 2  All things bearing a certain relation to other members of the set are also to count as members of the set. 3  It is this step that makes the definition recursive.
