[CODE] Integer partition function in Python (recursive and iterative)

The integer partition function p(n) is the number of ways of writing n as a sum of positive integers, where the order of the summands does not matter. Let's see how to implement it recurively and iteratively.

From recursive to iterative functions (step by step)

Recursive and iterative algorithms are two ways of solving problems. A recursive algorithm calls itself repeatedly until it reaches a base case, while the iterative one uses a loop to repeat operations until a condition is met. Both can achieve the same results but have different advantages and disadvantages. In this article, we will see how to turn a recursive into an iterative function step-by-step.
