Frequently Asked Questions
Is it a good choice to use recursion in Java interviews?
Recursion is often encouraged in Java interviews, but be mindful of performance and stack limitations, especially with deep recursion.
What are the advantages of recursion over iteration in Java?
Recursion simplifies code for certain problems, like tree traversals, but due to stack overhead, it may be less efficient than iteration for larger datasets.
What are the key recursion techniques I should know for Java interviews?
Focus on mastering basic recursion, tail recursion, and optimizations like memoization to handle complex problems efficiently.
What is a real-life example of recursion in programming?
Navigating directories in a file system is a real-life example of recursion. Each folder can contain files or subfolders, and traversing them mimics recursion.
How many types of recursion are there in Java?
In Java, recursion can be categorized into two types: direct recursion (where a method calls itself) and indirect recursion (where a method is called by another method in a recursive loop).
