Questions & Answers
Q: What is the basic concept behind generating Fibonacci numbers using recursion?
The concept involves breaking down the problem into smaller subproblems and using a base condition to determine the values at the starting points. Recursion is used to build upon the previously calculated Fibonacci numbers.
Q: How is the base condition defined in this program?
For Fibonacci numbers 0 and 1, the base condition states that their respective values are 0 and 1.
Q: How does recursion help in generating Fibonacci numbers?
If the input value is greater than 1, the program recursively calls itself for the values of n1 and n2, and then adds them together to obtain the Fibonacci number for n.
Q: Can you explain the flow of the program using an example?
Suppose we want to find the Fibonacci number for n=4. The program would recursively call itself for n=3 and n=2 to obtain fib(3) and fib(2). The program then adds these two values together to find the Fibonacci number for n=4.
Summary & Key Takeaways

Fibonacci numbers are typically generated using loops, but this program demonstrates how to use recursion to achieve the same result.

Recursion is achieved by breaking down the problem into smaller subproblems and solving them sequentially.

The program uses a base condition to determine the values of Fibonacci numbers at their starting points and builds upon them using recursion.
