That's old story. You, probably, know the answer.
I take a metro to go home after my long programmer's work day. It happens sometimes earlier, sometimes later. There are two metro lines going through the same Braddock Road Station - blue and yellow. I need the yellow train to go home. The trains are always alternating. But what a strange thing I noticed: in the most cases the blue line train comes in first. And I'm forced to wait more for the next one. Again, there is only one rail-road; blue and yellow trains always alternate.
1) How is it possible?
2) Does it mean that if I had to use blue train instead of yellow one, I would waste less time waiting?
You can post answer into my Guest Book. I wish you do not breake your mind thinking... Take it easy.
(This task went from one of Russian Math/Physic Olympiad. People, who already know it: if you feel, that my formulation of the task is not clear enough, please tell me how to make it better.

People, where are you? Where is the correct answer? Probably, I'll publish it here in a week or two... Take a last chance to solve this task by yourselves!

Hurrah! There is the right answer!

One year before, when I studied Borland Delphi at home, I made the small dll. It is Delphi 1.0 application that performs file/directory search on the all of subdirectories of the given one. Probably, I reinvented the weel when struggled with the algorithm. It is something like FIFO queue, as I understand it now after completing ZDU "More C++" course with Jesse Liberty (His interesting although buggy book is "Teach Yourself More C++ Programming in 21 Days").
I'm going now first to make sure, that everything is correct and is working with any host application, not only Delphi program. And I will post here the source code. Note, it does not use recursion that brought some advantages.

I'm novice in the Web Publishing. As I learn, I will publish here some tricks for novice Web Publishers like myself.
Note, how I wrote JavaScript to bring up background sound! (go to my Home Page to see other sub-pages). Those scripts play every day new MIDI file from the array. I use <BGSOUND> for MSIE and <EMBED> tag for Netscape Navigator.
