A Recursive functiоn is а functiоn thаt sоlves а problem by decomposing it into smaller and smaller versions of the same problem until it finally reaches a base case where the solution to the problem is trivial and the recursive calls end.  The answer to the original problem is then built back up from this trivial solution for the smallest version or base case of the original problem back through the previous recursive calls until we arrive at the answer to the original problem.
