Consider the grammars:
 a)
o S → aaS | bbS | abX | baX | ^
o X → aaX | bbX | abS | baS
 b)
o S → aSbb | abb
c)
o E → E + E | E * E | (E) | 7
o The terminals here are {+, *, (, ), 7}

For each of the above grammars solve the following
1. Show that it is LR(0)
2. If the grammar is LR(0) then Construct LR(0) Table and Execute one word from the language of grammar
3. Show that it is LR(1)
4. If the grammar is LR(1) then Construct LR(1) Table and Execute one word from the language of grammar
