Ulam Sequence Generation Via Recursion
The Recursive Ulam Sequence Generator is a feature that generates the Ulam sequence—a unique integer sequence—using a recursive algorithm. The Ulam sequence starts with two predefined numbers, 1 and 2, and each subsequent number is the smallest integer that can be expressed as the sum of two distinct earlier numbers in exactly one way. This feature provides a recursive approach to find Ulam numbers up to a given integer, maxN.
