Description

Fix fibonacci sequence logic to correctly return the n-th element. Currently, the function is incorrectly recursing on n-3 instead of n-2. This leads to incorrect results for larger values of n.

Changes

• Fix Fibonacci sequence logic in fibonacci.go file to correctly return the n-th element.

Overall, the code patch adds a recursive function to calculate the nth number in the Fibonacci sequence. Here are a few points to consider for code review:

• Naming: The function name and package name follow Go's naming conventions, which is good.
• Function signature: The function takes an integer input and returns an integer output. It would be helpful to add comments describing what exactly the function does and what inputs it expects.
• Logic: There is a bug in the code. The Fibonacci sequence is formed by adding the previous two numbers, so the last line of the function should be "return fibonacci(n-1) + fibonacci(n-2)" instead of "return fibonacci(n-1) + fibonacci(n-3)". This bug causes the function to return incorrect values for n >= 3.
• Performance: Recursive Fibonacci computations can become very slow for large values of n, since the function makes two recursive calls for each call. Consider adding memoization or using an iterative algorithm to improve performance.
• Documentation and testing: Adding documentation and tests would increase the reliability and maintainability of the code.

Overall, the code could benefit from further improvement, but it provides a basic implementation of the Fibonacci sequence computation.
