Coding Challenge: Caching
Explore how to enhance the performance of Python's Fibonacci calculations by implementing a simple dictionary-based cache. Learn to optimize recursive functions for large inputs, reducing computation time significantly.
Problem
You have been given a fib() function that calculates the nth number in the Fibonacci sequence. The function works correctly with smaller numbers such as 4, 5, 10, etc. However, when we want to calculate the numbers much ahead in the series such as ...
