Recursion
Recursion Re*cur"sion (-sh?n), n. [L. recursio. See {Recur}.] 1. The act of recurring; return. [Obs.] --Boyle. [1913 Webster]

2. (Math.) The calculation of a mathematical expression (or a quantity) by repeating an operation on another expression which was derived by application of the same operation, on an expression which itself was the result of similar repeated applications of that same operation on prior results. The series of operations is terminated by specifying an initial or terminal condition. [1913 Webster]

3. (Computers) A programming technique in which a function calls itself as a subfunction. Such calls may be repeated in series to arbitrary depth, provided that a terminating condition is given so that the final (deepest) call will return a value (rather than continue to recurse), which then permits the next higher call to return a value, and so forth, until the original call returns a value to the calling program. [1913 Webster]
