What is a recursive algorithm?
Understand the Problem
The question seems to ask for an explanation or definition of a recursive algorithm, potentially looking for its characteristics or examples of how it functions in programming.
Answer
A recursive algorithm calls itself with smaller inputs to solve a problem.
A recursive algorithm is an algorithm that solves a problem by calling itself with smaller or simpler input values and obtaining the result for the current input by performing basic operations on the returned values.
Answer for screen readers
A recursive algorithm is an algorithm that solves a problem by calling itself with smaller or simpler input values and obtaining the result for the current input by performing basic operations on the returned values.
More Information
Recursive algorithms are often used in computer science to simplify complex problems by dividing them into smaller, more manageable subproblems. This technique is widely used in data structures like trees and in algorithms for searching and sorting.
Tips
Common mistakes include not defining a base case, which can lead to infinite recursion, and not simplifying the input correctly with each recursive call.
