Course Introduction：Recursive definition and optimization: Recursive: A function calls itself internally to solve difficult problems that can be decomposed into smaller sub-problems. Tail recursion: The function performs all calculations before making a recursive call, which can be optimized into a loop. Tail recursion optimization condition: recursive call is the last operation. The recursive call parameters are the same as the original call parameters. Practical example: Calculate factorial: The auxiliary function factorial_helper implements tail recursion optimization, eliminates the call stack, and improves efficiency. Calculate Fibonacci numbers: The tail recursive function fibonacci_helper uses optimization to efficiently calculate Fibonacci numbers.

Course Introduction：The programming technique in which a program calls itself is called recursion. Generally speaking, recursion requires boundary conditions, a recursive advance section and a recursive return section. When the boundary conditions are not met, the recursion advances; when the boundary conditions are met, the recursion returns.

Course Introduction：The recursive algorithm solves structured problems through function self-calling. The advantage is that it is simple and easy to understand, but the disadvantage is that it is less efficient and may cause stack overflow. The non-recursive algorithm avoids recursion by explicitly managing the stack data structure. The advantage is that it is more efficient and avoids the stack. Overflow, the disadvantage is that the code may be more complex. The choice of recursive or non-recursive depends on the problem and the specific constraints of the implementation.

Course Introduction：Recursion is a technique where a function calls itself, but has the disadvantages of stack overflow and inefficiency. Alternatives include: tail-recursion optimization, where the compiler optimizes recursive calls into loops; iteration, which uses loops instead of recursion; and coroutines, which allow execution to be paused and resumed, simulating recursive behavior.

Course Introduction：Function recursion is when a function calls itself, providing an effective way to solve complex problems by decomposing the problem into sub-problems. It is crucial to optimize recursion to avoid stack overflow. Common optimization techniques include: Limiting recursion depth Using tail recursion optimization Using memos to avoid double calculations
