☼ With pen and paper, manually trace the execution of a recursive descent parser and a shift-reduce parser, for a CFG you might have already seen, or certainly one of your own devising. A simple bottom-up parser is the shift-reduce parser, which shifts input onto a stack and tries to match the gadgets on the high of the stack with the proper hand aspect of grammar productions.
