Friday, May 22nd

Regular class today. 

I came in and ended up going to Mr. Daly during the first five minutes of class, since I still couldn't figure out the problem that I had last time. We managed to fix that problem, and I will be showing it at the end of the blog. 

However, I have decided that for the remainder of the year, I will not be working on Level 3. I've decided that I want to solidify my knowledge at the second level completely before moving on to Level 3. Most likely during the course of the year in AP Computer Science, I'll do some level 3 problems to practice, if the new teacher doesn't already ask us to do them for the class. Although I'm pretty comfortable with what CodingBat asks of me at level 2, I still want to practice a bit more before moving on. 

After completing the problem, I went outside to help Matan, Natalie, and May with their rap. I rapped two lines for them, and then went back inside.

I came back in, and Tommy was stuck on a problem. It asked him to add all of the numbers of the array, but to leave out numbers that were in the range of after a 6, and before a 7. He did not know what to do, so he asked for my help. I taught him the concept of flagging, with booleans. I felt good after teaching him because I knew that he understood. 

Following this, Mr. Daly gave me and AP Computer Science packet, and told me that there was a problem or two that I would be able to complete. I completed one of them quickly, as it was relatively easy ( it was exactly like Tommy's problem), and began to work on the second one but didn't have time to finish it since class was ending. I will be looking at it at home to see what I can do.

This is the problem that Mr. Daly and I completed : 

----------------------------------------------------------------------------------------------------------------------------------

Given two arrays of ints sorted in increasing order, outer and inner, return true if all of the numbers in inner appear in outer. The best solution makes only a single "linear" pass of both arrays, taking advantage of the fact that both arrays are already in sorted order. linearIn({1, 2, 4, 6}, {2, 4}) → true linearIn({1, 2, 4, 6}, {2, 3, 4}) → false linearIn({1, 2, 4, 4, 6}, {2, 4}) → true

Looking forward to continuing. Next class (I think) I am presenting. See you then !
