Recursion
Recursion
A programming concept where a function calls itself within its own definition.
Recursion vs. Iteration
Recursion vs. Iteration
Recursion does not require a loop structure, and is based on repeated function calls.

Study Notes
Recursion and Iteration
- Recursion is a programming concept where a function calls itself.
- The main characteristic of recursion that distinguishes it from iteration is that recursion uses function calls to solve a problem, whereas iteration uses loops.
- A common concern when using recursion in programming is stack overflow, which occurs when the function calls itself too many times, exceeding the maximum stack size.
- Recursion can be less efficient than iteration due to the overhead of multiple function calls, which can lead to increased memory usage and slower performance.
- Iteration, on the other hand, allows a program to repeatedly execute a block of code using loop structures, such as for loops or while loops.
