The objective is to transfer entire tower one of other pegs rightmost in applet below moving only disk at time and never larger onto smaller. The recursive solution above involves moving twice disks from one peg to another and making additional move between.

Read More →The algorithm actually provides another nonrecursive solution to puzzle. Since we are trying to use as few steps possible may assume that portion of the task took exactly TN moves. For N it translates into Move from Src Dst Aux Of course means moving the topmost disk

Read More →The function is recursive in that it calls itself repeatedly with decreasing values of until terminating condition our case has been met. Reference A. onze r h i a l sj evt nd u typeof if b assList pd sp et c k w function return we . At this point time all the remaining disks will have to be stacked decreasing size order on Aux

Read More →TN is defined terms of only one its preceding values. We are given tower of eight disks initially four the applet below stacked increasing size on one three pegs. Its solution touches two important topics discussed later recursive functions and stacks recurrence relations The applet has several controls that allow one select number of disks observe in Fast Slow manner. Indeed when the time comes to move bottom disk smaller disks will have been moved from Src Aux at least TN moves. The applet expects you to move disks from leftmost peg rightmost . N

After moving the bottom disk from Src Dst these disks will have be moved Aux . One then needs exactly TN more steps to finish task. Buy this applet What if does not run Recursive solution call the three pegs Src Source Aux Auxiliary and Dst Destination
