<ul><li>The Happy Number problem asks us to determine if a given positive integer n is a happy number, defined by repeatedly replacing the number with the sum of the squares of its digits until it reaches 1 or enters a cycle.</li><li>Implemented getNext transformation calculates the sum of squares of a number's digits efficiently.</li><li>Cycle detection involves using a HashSet to store generated numbers, checking for repeats before calculating the next number to identify cycles.</li><li>Utilizing Floyd’s Cycle-Finding Algorithm provides an optimized O(log N) time complexity and O(1) space complexity solution for the Happy Number problem.</li></ul>
