Anyone who has been a part of a Computer Science program at a university will probably have dabbled with Fibonacci in their first semester of school. With that said, I think this can be a refresher to anyone going through the interview process for a programming or software engineering position.
There are number of different languages you can accomplish this task with. The interviewer may even ask for a pseudo-code alternative rather than language specific.
By definition, the first two numbers in the Fibonacci sequence are either 1 and 1, or 0 and 1, depending on the chosen starting point of the sequence, and each subsequent number is the sum of the previous two.
An example of the sequence can be seen as follows: The first two numbers in our sequence are zero and one.
The goal is to find the Fibonacci number at a certain sequence index, which in this example is fifteen. Every loop iteration we are summing the previous two sequence values, then pushing our values up in a sense. By this I mean that a is dropped off and replaced with b and b is replaced with the current index value of the sequence, being our new sum.
When our loop has reached our desired fifteen index, we can return whatever the new sum value is. In the above code, we are going to plan on receiving the sequence value at index five because anything larger is going to be rough for me to type out.
You can break this down like the following: At the furthest breakdown, our sum turns into five which is the Fibonacci number at index five.
Conclusion Know how to do this task. It is a good interview question because it demonstrates your understanding of recursion and looping as well as your thought process in choosing between the two.
