Tuesday, May 26th

Today was not my turn at the genius bar, but we still worked in the library, because there was MAP testing in our regular classroom. It was nice though. It was an efficient class. I didn't do anything special, but got a lot done. I managed to finish the problem in the AP booklet, which actually turned out to be a lot easier than expected. I will be showing it in the blog.

After showing it to Mr. Daly, he suggested that I try some more AP problems from Georgia Tech. We looked at some together (they were multiple choice problems), but we figured that they involved things that I didn't understand and hadn't learned yet, so I decided that I would work on the AP-1 section in CodingBat.

I went back to sit with Tommy and Preston. I helped Tommy out with a problem. I forget which one exactly, but it was an Array 2 problem. While I wasn't helping the two, I was working on my AP-1 problems, which were also relatively at my level. I was working on them, and I noticed that I didn't really need help. I didn't always get the problems the first try, but I knew what to fix most of the time and what logic to use. I felt for once like I was the teacher at the table with Preston and Tommy. It was a good feeling. When Tommy showed me his problem, I knew how to solve it in a split second. It's nice to know that I've improved from 2 months ago where I was also struggling to complete an Array 2 problem.

Before I show the problem, I also realised that for last class's blog, I wrote that I was presenting today. I was wrong about that. Turns out I will be presenting on Monday.

Here is today's problem.

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

Here is the code rewritten, so that it is clearer:

public String getHint (String guess, String hidden){

String str = new String("");

for (int i=0;i<guess.length();i++)

{

     if (!hidden.contains(guess.substring(i,i+1))

{

               str+="*";

}

     if (hidden.contains(guess.substring(i,i+1) && !(hidden.substring(i,i+1).equals(guess.substring(i,i+1)))

{

    str+="+";

}

      if (hidden.substring(i,i+1).equals(guess.substring(i,i+1))

{

        str+= hidden.substring(i,i+1);

}

return str;

}

}

Looking forward to next class !
