Iterative solution to Towers of Hanoi problem
Towers of Hanoi is a simple programming riddle often used in programming courses to introduce recursion. Not many people are aware that Towers of Hanoi has... »
Iterative algorithm for drawing Hilbert curve
In this post I will describe how to draw Hilbert curve iteratively. To avoid recursion we will use `hindex2xy` algorithm that translates Hilbert curve node index... »
