- 2.d. Construct NDPDA for the language: L= {albickd! | i=k or j=l, i, j, k, 1 >=1}3. Consider the abstract syntax for the following expression language. The constant Zero denotes 0, and the operation Succ computes successors. The operation Sum takes a list of expressions as arguments and computes its sum. IfPos returns the value of the first expression if its value is greater than 0. Otherwise, it returns the value of the second expression. You may use the function sum :: [Int] -> Int in your solution. data Expr = Zero | Succ Expr | Sum [Expr] | IfPos Expr Expr Define the semantics of the expression language as a function sem of the following type. sem :: Expr -> IntPython Need help with code A rule has three parts: •name –a simple name for the rule (e.g., up, left, down, right) •precondition function –a Boolean function that accepts a state and returns true if the rule is applicable to state •action function –a function that accepts a state and returns the successor state obtained by applying the rule. You can use these rules to implement functions such as applicable-rule, which returns a list of the rules applicable to a given state, and successor-state, which returns the successor state for a given state and rule. Question: Encode the rules for the sliding-tile puzzle. Remember that it is easiest to consider moving the empty space up, left, down, or right. Using these rules, write routines to determine the rules applicable to a state and the successor state given a state and rule to apply. Note that you could implement these as iterators or have them return lists (or vectors) or rules and states.
- A(n) ------------- declaration imports one static member.Q3: Design machine M to recognize the language L= {w E (a, b)* every a in w is followed by at least two b'}The C struct, Exercise In C++: The programming assignment at the end of this module will involve a struct named Square with exactly one attribute representing the length of one of its sides as a numeric data type. Square objects will have exactly one supporting function to calculate the area and perimeter of a Square object, with two parameters -- an ostream object by reference, and a Square by constant reference. The function should send to the ostream object: the side's value, labeled without rounding, followed by the area and perimeter, both labeled and rounded to two decimal digits. (Note that this function may be called several times from a main program, and still the side should be output with any formatting removed!) Write two code blocks -- one for the struct and its supporting function's prototype, and another for the function definition itself. Assume that all needed library includes have already been made. Do not write a full working program or int main() -- just…

It is possible to declare multiple variables separated by commas in one statement. The following statements present examples, double b; double a, z, w: The following partial grammar represents the specification for C++ style variable declaration. In this grammar the range a-z indicates terminals that represent variable names. A variable name consists of only one letter. The non-terminal S is the start symbol. S=TV: V=C, VIC T = float C = a-z We want to design an LR parser for this grammar. Create a complete parsing DFA, showing the closure for all states including the parsing marker in every rule, and transitions between the states. You can use the symbol @ as the parsing marker. States need to be numbered or named. You may write all required information in a table instead of drawing a DFA. There is no need to add $ at the end…Write a segment code in any language you prefer that behaves differently if the language used structural equivalence two types as the same if they consist of the same components. name equivalence each type declaration introduces a new type, distinct from all others. declaration equivalence two types are equivalent if they lead back to the same type.
