HistoryThe history of mathematical puzzles in coding can be traced back to ancient civilizations, where early mathematicians and scholars engaged in various intellectual games and challenges. The concept of mathematical puzzles has evolved over centuries, influenced by cultural exchange and technological advancements. One of the earliest recorded mathematical puzzles is the "Babylonian Square Puzzle," found on a clay tablet dating back to around 1800 BCE. This puzzle involved finding the dimensions of a square given its area, exemplifying the ancient Babylonians' interest in mathematical problemsolving. In medieval times, the Islamic Golden Age saw significant contributions to mathematics and puzzlesolving. Scholars like AlKhwarizmi and Omar Khayyam made substantial advancements in algebra and geometry, which laid the foundation for more complex mathematical puzzles. During the Renaissance, mathematicians such as Leonardo da Vinci and Leonhard Euler contributed to the development of mathematical puzzles and recreational mathematics. Euler, in particular, is famous for his work on graph theory, which gave rise to the concept of the "Seven Bridges of Königsberg" problem. In the 20th century, the advent of computers and programming languages opened up new possibilities for mathematical puzzles in coding. Early computer scientists, like Alan Turing, tackled puzzles related to computation and decision problems, which laid the groundwork for modern algorithms and coding challenges. With the proliferation of the internet and online communities, mathematical puzzles in coding have become popular among programmers of all levels. Coding platforms and websites offer a vast array of challenges, encouraging enthusiasts to explore and solve problems rooted in mathematics and logic. In conclusion, the history of mathematical puzzles in coding reflects the continuous exploration of human intellect, from ancient civilizations to the modern digital era. These puzzles have not only entertained and engaged generations but also played a significant role in advancing mathematics and computer science, making them an integral part of the everevolving world of coding. The Tower of Hanoi problem is a classic mathematical puzzle that consists of the following setup: You are given three pegs (or rods) labeled A, B, and C. On peg A, there is a stack of n disks, each of a different size, arranged in increasing order of their size from top to bottom. The goal of the puzzle is to move all the disks from peg A to peg C, using peg B as an auxiliary, following three simple rules:
The Tower of Hanoi problem has a recursive solution, and the challenge is to find the minimum number of moves required to transfer the entire stack of disks from peg A to peg C while adhering to the rules. The Tower of Hanoi puzzle is not just a recreational problem; it has realworld applications in computer algorithms, recursion, and problemsolving strategies. It also serves as a fundamental example in teaching the concepts of recursion and algorithm design. Example:Algorithm for tower of Hanoi:Follow the steps below to solve the problem:

Time and Space Complexity Analysis Time Complexity: The time complexity of the Tower of Hanoi algorithm is often expressed using the recurrence relation. In this case, let T(n) be the time complexity for solving the Tower of Hanoi problem with n disks. The recurrence relation is given by: T(n)=2T(n1)+1 Here, the algorithm makes two recursive calls to solve the problem with n1 disks, and it also performs a constant number of operations (printing the move). The recurrence relation indicates that the time complexity is exponential, specifically O(2n). This is because each level of recursion doubles the work done, resulting in an exponential growth in the number of operations as the number of disks increases. Space Complexity: The space complexity is determined by the amount of memory used by the program, especially in terms of function call stack space during recursion. In this code, the primary use of memory comes from the function call stack, as each recursive call adds a new frame to the stack. For the Tower of Hanoi problem, the maximum depth of the recursion is n, corresponding to the number of disks. Therefore, the space complexity of the algorithm is O(n), as it requires space proportional to the number of disks to keep track of the recursive calls. It's important to note that the space complexity is linear with respect to the number of disks, making it more manageable than the time complexity. However, the time complexity remains exponential, making the algorithm less efficient for large numbers of disks. The Tower of Hanoi problem highlights the tradeoff between time and space complexity in recursive algorithms, as the recursive nature simplifies the code but can result in exponential time complexity.
