This is a nice problem to practice. The key idea is to count occurrences of each number and then check adjacent values (x and x + 1). Instead of comparing every pair, using a frequency array or map makes the solution efficient and easy to understand. The approach is a bit like following a Minecraft Jenny Mod guide, where step-by-step organization makes complex tasks simpler.
