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 mplement it in Q6. The output must print the LR-parsing table. Grammar:

Compilation Techniques Given RE as follows: (ab | b*) a*b Asked:a. Make a complete syntax tree with firstPos and lastPosb. Make the DFA and draw the result
how you would add the symbol "-" minus to the alphabet of the LR parsing table means "HOW" you would do it , what would you use as a template? How would you walk through the process and would you have to add to the grammar as well? if so, what would you add?
