1.Given that, L = { start of all strings over a, b }. Construct CFG from this language.2.Determine the FIRST and FOLLOW sets from the production rules you used to construct the parse table.       S --> A $       A --> - A B | id C       B --> - B | " "       C --> " " | id

Try to ans in 20 min and don't copy ans from internet or any ai tool its wrong one solution if you do so you will get downvote give accurate answer

Stack is a linear data structure which follows

3 CNF Step 3Perform step three of converting the following CFG’s into CNF by removingunit rules.3.aV = {S,A,B}, Σ = {a,b}, S = S, R =S →AA →AA |AB |A |B |aBB →BB |Bb |b

No credit for late submission Your task for this assignment is to implement a stack data structure in C++. This may be accomplished by utilizing the C++ standard template library (STL) or by utilizing a user-defined class. 1. Implement a transaction-based stack data structure using C++. The program will be interactive. Data transactions will be entered at the command line and results will be displayed on the console. Each input transaction will contain an arithmetic expression in post-fix format. Assume that each operand and operation (+, -, *, /, %, ^) is a single character in each arithmetic expression without spacing. You may assume that each arithmetic expression is correctly formatted. However, your program should not attempt the following: a. Divide by zero with / or % ... Instead, your program should display an error message and then begin evaluating a new input transaction. b. Perform % with non-integer operands 2. .. Instead, your program should display an error message and…

make descriptive and clear presentation of the ADT Consider an ADT for the data structure of positive integers called POSITIVE INTEGER defined over a domain of integers Z, supporting the operations of addition (ADD) and subtraction (MINUS) and checking if positive (CHECK_POSITIVE). The ADT is defined as follows: L = Z+, D = {x|x € L}, 0 = {ADD, MINUS, CHECK_POSITIVE}.
