What is a recursive algorithm in computer science?
Understand the Problem
The question is asking about the concept and implementation of recursive algorithms in computer science. It requires a description of what a recursive algorithm is, examples, and how it works.
Answer
A recursive algorithm calls itself with smaller input values.
A recursive algorithm is an algorithm that calls itself with smaller or simpler input values, solving a problem by applying simple operations to the result obtained from these smaller instances.
Answer for screen readers
A recursive algorithm is an algorithm that calls itself with smaller or simpler input values, solving a problem by applying simple operations to the result obtained from these smaller instances.
More Information
Recursive algorithms are commonly used for problems that can be broken down into similar smaller problems, such as calculating factorials, Fibonacci numbers, and traversing data structures like trees.
Tips
A common mistake is forgetting to include a base case in the recursive algorithm, leading to infinite recursion.
