Webrecursive process with a single subproblem and no glue step. • Each recursive method call is a tail call -- i.e., a method call with no pending operations after the call. When all recursive calls of a method are tail calls, it is said to be tail recursive. A tail recursive method is one way to specify an iterative process.
