The Tower of Hanoi puzzle, created by Édouard Lucas in 1883, demonstrates recursion in algorithmic problem-solving. It involves moving disks between pegs under strict rules, with a recursive strategy that simplifies the complex task. While the recursive solution is elegant, it has exponential time complexity, making it impractical for large numbers of disks. Alternative non-recursive methods also exist, offering different problem-solving perspectives without changing the puzzle's inherent complexity.
