In this program, the “fibonacci” function is a recursive function that returns a list containing the first n Fibonacci numbers. The base cases are when n is 0 (returns an empty list), 1 (returns [0]), or 2 (returns [0, 1]). For values of n greater than 2, the function ...
Python Copy In this example, the memoize function creates a closure (wrapper) that caches the results of calls to the fibonacci function. This optimizes the performance by avoiding redundant computations. Data Hiding and Encapsulation: Closures can be used to create private variables, encapsulating ...

The Fibonacci sequence is named for Leonardo Pisano (also known Fibonacci), an Italian mathematician who lived from 1170 to 1250. Fibonacci considered the sequence to be an answer to the following question: "How many pairs of rabbits will be produced in a year, beginning with a single pair,...

The lru_cache decorator is a built-in tool in Python that caches the results of expensive function calls. This improves performance by avoiding redundant calculations for repeated inputs. Example: from functools import lru_cache @lru_cache(maxsize=128) def fibonacci(n): if n < 2: return n...
