Recursion. Recursive functions. What are they used for and how they helpful?
A recursive function is a function that calls itself during its execution. This allows the function to repeat its actions until a certain condition is met.
Some benefits of using recursive functions include simplifying complex problems, making code more readable and maintainable, and reducing the need for repetitive code.
Recursive functions are commonly used in computer science for tasks such as traversing data structures (e.g. trees), sorting algorithms, and solving problems that can be broken down into smaller subproblems.
Yes, recursive functions can potentially cause performance issues if not implemented carefully. Each time a function calls itself, it adds a new layer to the call stack, which can lead to memory and performance issues if the function is called too many times.
Yes, there are alternative approaches to solving problems that can be solved with recursive functions. These include iterative solutions, which use loops to repeat actions, and dynamic programming, which uses memoization to store previously calculated values and avoid repetitive calculations.
