Give examples of two functions that are not completely tail recursive but are almost tail recursive. Describe a general pattern for turning an almost tail-recursive function into a loop in the same way that a tail-recursive function can be transformed. Can an interpreter recognize almost tail recursion as easily as tail recursion? Explain
