WebRecursion is a separate idea from a type of search like binary. Binary sorts can be performed using iteration or using recursion. There are many different implementations for each algorithm. A recursive implementation and an iterative implementation do the same exact job, but the way they do the job is different. Web0. Functional languages are better at two very specific kinds of recursion: tail recursion and infinite recursion. They are just as bad as other languages at other kinds of recursion, like your factorial example. That's not to say there aren't algorithms that work well with regular recursion in both paradigms.
