I didn't write any code this week, but spent my time reading about LL and LR parsers. I have some questions about the differences between LL and LR, so if we could discuss that a bit I could start writing a parser for our next meeting. I was thinking about writing a lexer and parser combo for a simple calculator, but did not have time to implement this week.
You need to stare at and work through an example with explanation, like https://stackoverflow.com/questions/5975741/what-is-the-difference-between-ll-and-lr-parsing .
