Question

Q5. [25] The bottom-up parsing uses an LR-parser. Show a complete LR-parse, including parse stack
contents, input string, and action for the string a * (a + a) that ends with a marker '$', using the following
grammar of the expression and the parse table below. Complete your parsing in the given empty table. -
Refer to the handout, LR-parsing-Action-GOTO.pdf. If you'd like to, you can write a program to
implement it in Q6. The output must print the LR-parsing table.
Grammar:
1. E→E+T,
