Show that the following grammar is ambiguous. Hint: Show two different leftmost or rightmost derivations for the same string. Equivalently, you can show two different parse trees for the same string. <expr> ::= <expr> + <expr> | <expr> - <expr> | <expr> * <expr> | <expr> / <expr> | int int ::= 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 Using this grammar show that ambiguity is not acceptable...
Please actually answer it
For both of the following languages, provide a grammar that generates it, an intuitive explanation why this grammar generates this language, and a graphical representation of a push-down automaton that recognizes this language. (a) The language of properly nested sets of parentheses over the alphabet G)). Note that the string (COO))) belongs to this language, while the string (O) () does not because the third closing parenthesis does not have a matching opening parenthesis. Provide a...
The questions in this section are based on the grammar given as the following: prog -> assign | expr assign -> id = expr expr -> expr + term | expr - term | term term -> factor | factor * term factor -> ( expr ) | id | num id -> A | B | C num -> 0 | 1 | 2 | 3 (2a) What is the associativity of the * operator?

1. In a language, each sentence is a string starting with a capital letter followed by two or more small letters and ending with three or more digits. Example sentences are Abc001, Zyxw9876 etc. a) Write a BNF grammar for the language. b) Show the derivation and the parse tree of the string Test3501. 2. Augment the following BNF to write an attribute grammar. Assume the only possible variable types are integer and float. The language rules are as follows:...

S → ABC A → aA|aa B → bB|B C → cC|cccc Q2: Describe the strings generated by the following grammar S → aSa S → bSb S → aa S → bb Q3: Consider the following grammar: S → ABC A → aA|a B → bB|b C → cC|c Change the above grammar such that it generates L1={anbmck; n>=3,m>=3,k>=4} Q4: Use the following grammar...
(20 pts) To understand the value of recursion in a programming language: implement the binary search algorithm first as a recursive function and again using a conditional loop. Your program should create an array of characters holding the letters ‘A’ – ‘Z’ and find the index in the array where the letter ‘K’ is stored. You may use any programming language that supports recursion. (5pts) Define syntax and semantics and give an example. (5pts) Why is it important for a...
