Its been another two week cycle.

after the fiasco of the Songlist ME, i gave them the same ME for ME20, just so that they could try the problem out by themselves. ME18 and 19 were bonus MEs just so that they could feel better with a sense of accomplishment...

ME 21 was what i called converyor belt. its a conveyor belt with 6 int slots, the method int move(int i) enters a new integer, which pushes an integer out. A public String toString() outputs a representation of the entries.

From here is the jump point for ME 22 and ME 23, Stacks and Queues. I gave this to them over a long weekend so that they could figure out the algo by themselves. Come monday, i checked their exercises and then discussed the algorithm.

the next two weeks will be stack and queue related exercies. the lesson here is that they do not have to rewrite code that they have done already.
