Check if a Number Is a Happy Number in Java

Date: 2024-05-13

This Java Code Geeks article explains how to determine if a number is "happy" (repeatedly summing the squares of its digits eventually results in 1) or "sad" (it doesn't). The article presents two Java code examples: a basic iterative approach and a more efficient solution using Floyd's Cycle Detection Algorithm. Both methods are detailed, illustrating the interplay between mathematical concepts and programming solutions. The article highlights the problem-solving aspects and the efficiency gains achievable through algorithmic optimization.
