Here is the LR(1) Parsing Algorithm that uses the LR(1) Parse Table with a stack to parse strings. For this stack we do not use a stack start symbol, but instead assume this stack can determine whether it is empty or not. An entry in the LR(1) Parse Table has possible multiple parts including an action (s for shift, r for reduce, g for goto, acc for accept, or e for error), a state, a right-hand side (rhs) of a production, and a left-hand side (lhs) of a production. The functions get(), top(), pop(), and push() were defined in Section 16.2.

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
