Friday- Unusual Substitution

  Today Mr.Arkin wasn't present for computer science. It is not a usual sight, I believe a substitute has filled in for Mr.Arkin only twice out of the 10 weeks of school! Today I worked on five of the Repetition assignments, however I was baffled by the sixth, because I did not know how to use an accumulator. I will do my best to figure it out and if I was not able to then I will ask Mr.Arkin on Monday. I really want to get Repetition over and done with so I can carry on to the next set of assignments, which I believe are related to either Substrings or Mr.Arkin will teach a new lesson and give a new set of assignments.
