How to avoid the possibility of endless loop.

For instance, binary search tree, binary tree, tree, etc***( to be continued)* . In math, closure, natural numbers. - recursive optimization
dynamic programming - function
Fibonacci function: either iterative or recursively is OK
Ackermann function: cannot be easily expressed without recursion - structural induction
a powerful generalization of mathematical induction widely used in mathematical logic and computer science - factorial
- in programming language
