Start_y - peg_height * i, # Pegs are one on top of the other, height depends on iterationĭef visual_hanoi_simulation(number_of_pegs, base_width, peg_height, sleeping_interval): Start_x (SPACE_PER_PEG - pegwidth)/2, # Handles alignment putting pegs in the middle, like a piramid (255-pegwidth, 255-pegwidth, 255-pegwidth), A trivial solution to Double Decker is to simply treat it as a standard instance of the Tower of Hanoi with 2n disks and, thus, will need the usual 2 2n 1 4n 1 move. I'll just state the algorithm here.You may need to know the stack data structure in C to implement it There are three poles.The source pole,The auxiliary pole and The Destination pole. Like in a piramid, the smaller in lighter color. Answer (1 of 6): Yes ,the Tower of Hanoi problem can be solved using iteration in C. Given a pile of pegs, displays them on the screen, nicely inpilated Initially all the disks are stacked on the first tower. The disks can be moved from one peg to another. The problem setup consists of three rods/pegs and n disks. > for position in hanoi(,, ], 0, 2, 3): print positionĪssert len(pegs) >= n, 'not enough disks on peg'Īux = 3 - start - target # start target aux = 3įor i in hanoi(pegs, start, aux, n-1): yield iįor i in hanoi(pegs, start, target, 1): yield iįor i in hanoi(pegs, aux, target, n-1): yield iĭef display_pile_of_pegs(pegs, start_x, start_y, peg_height, screen): The Tower of Hanoi is a classic problem in the world of programming. The sequence of optimal steps that leads to the solution. This function, given a starting position of an hanoi tower, yields #HANOI TOWERS WITHOUT RECURSION CODE#The code is pretty simple, tested and documented, so no further introduction is needed. The logic of the solving is taken from StackOverflow (see links in docstring), I wrote the part dealing with the graphics, so review is most welcome on the graphical part that I wrote. The rules of the problem require that these lists must always be decreasing sequences.I wrote a program to show graphically the solution of the problem of the Tower of Hanoi. The initial state of the system, with all discs on pole A is denoted by, for example, A = where the first indexed item is the "bottom" of the pole and the last indexed item is the "top". In the following code, we identify the discs by the integers $1,2,3,\cdots$ stored in one of three lists, A, B and C. The second step is a single move, but the first and last require the movement of a stack of $n-1$ discs from one peg to another - which is exactly what the algorithm itself solves! Move discs $D_1, D_2, \cdots, D_$ from B to C.Label the discs $D_i$ with $D_1$ the smallest disc and $D_n$ the largest. The problem can be solved using the following recursive algorithm. It is necessary to use the second pole (pole B) as an intermediate resting place for the discs. The task is to move the stack to the third pole (pole C) by moving one disc at a time in such a way that a larger disc is never placed on a smaller one. The famous Tower of Hanoi problem involves three poles, one of which (pole A) is stacked with $n$ differently-sized, circular discs, in decreasing order of height with the largest at the bottom.
