Week 5




Here is my finished Parser. I can't run it quite yet because I need to finish my bison code so that it will run. What I'm doing in this parser is taking my BNR Grammar and converting in to readable code for bison so it can follow my grammar and find things like loops, assignment statements, etc. You can see at the top I take my tokens for the operators and words that my program will you. We then have start of the grammar, "statement list" the broadest term in the grammar, which leads to questions, what is a statement list? following statement list we have its definition as " " or statement followed by a statement list(recursion so you can have as many statements as you'd like without coming with an error). Next, we need to define a statement, we define a statement as either an assignment statement, conditional statement(if then), loop statement(while),block statement, expression, and function call. Now we have multiple things to define, which will bring up other tiny question, which can be solved without adding too much problem. Following the code you will see how I define each statement and how I tackle the tiny questions that need to be solved. Finally, we arrive at the operators which is the final thing I define and finishes my parser for my tiny language.

    Great work this week, can't wait to see when you get Parser to run!

Week 9

 Today I looked at some interesting videos of some leetcode videos, which use problems that show up at coding interviews. I watched a guy who was prepping for interviews by running through these problems and talking about them. First Video was about locating islands. (pic of the instructions below) So hopefully you can see how the first input has only one island because all the ones are surrounded by zeros. It's kinda hard to see at first but it helped when he points out why in the video. He talks about the problem and comes up with a pretty straightforward solution. He says he will use a breadth first search(BFS), which I've done a bit of research on before in my week 6 of last years blog. Breadth first search when used on binary search trees takes a node and searches all of its nodes, so I can see how it can apply to this problem. Breadth first search will take one island(1) and search all the 1s connected, which is an island, so when it can't find anymore it means there ...

 This week I found an interesting problem that was exactly like a problem I did in my class this semester, csc 230, but instead of mips I did it in java. The problem is fizzbuzz where you take a number and if the number is a multiple of 3 print fizz and it its a multiple of 5 print buzz and if its a multiple of both print fizzbuzz. There are two method one(first one) is the one that was in a video where I discovered the problem and the second one is me doing it the way I thought of. The problem was pretty easy but the way it did intrigued me because It was different than mine his felt much more clever than mine. What he does is creates variable fizz and buzz so when fizz equals 3 and buzz equals 5 we reset and add to the arraylist but its cool that he does this by using variables to keep track of the fizz and buzz. So fizz for the first 10 will look like this 0,1,2,0,1,2,0,1,2,0,1 for buzz its 0,1,2,3,4,0,1,2,3,4,0 at all zeros after the first zero will add the respective word....

 Today I did another leetcode problem. Like last week I found a similar problem to one I've done in class but with a different language but instead of mips this time it is in C++. I'm starting to think my 240 teacher was making us do these problems on purpose haha... anyway, the problem this time is called valid parenthesis or matching brackets is what my 240 teacher called it. I knew the basic rundown of the problem and tried to code it. But to give a brief rundown we are checking if all brackets "("  or "{"  or "[" are closed correctly. Fortunately, I was able to directly translate the code for the most part, so we can see the tiny differences between c++ and java.  We see in the two pictures below that c++ looks a little different. In java we see the stack as new stack but in C++ #include stack and we dont need to new. In C++ the string as treated a char arrays so we dont need to do charAt in C++ they already are characters and in this respect i...
