Spiral Walk Exposed

Report published in the Proceedings of the National Conference on "Education and Research in the Information Society", Plovdiv, May, 2015

Traversing a matrix along a spiral is a popular small programming problem, but one which is often solved incorrectly, or only partially, or in an ill-structured way. To benefit teaching and learning good programming style, we considered worthy to present the construction of several solutions to this problem in an expository manner. Some related combinatorial problems are also discussed. Hopefully, the text can be useful to high and higher school teachers and students, as well as to practicing programmers.
