Consider the following Haskell datatype definitions for representing simple lambda calculus terms. data Term = Var String | Application Term Term | Lambda String Term   Define a function: freeVars :: Term -> [String] that gives a list of “Free Variables” in a term

Create Code in C++ For String searching algorithms – Boyer-Moore and Aho-Corasick – to find the occurrences of a particular string within a large body of text. For example, you might take a webserver log file and use an appropriate data structure to track how many times each page has been accessed.

A strongly-typed data type implementation supports strongly-typed data, whereas a loosely-typed data type implementation supports loosely-typed data.

Differentiate between structures and unions in C. Consider the following C structure forholding a 3-D vector:typedef struct v3d_tag{float x;float y;float z;} vector3D;Write a C function that takes two vector3D structures as arguments and prints their dotproduct.Note: For two vectors a = (a1,a2,a3) = a1i+a2j+a3k and b = (b1,b2,b3) = b1i+b2j+b3k, where i,j and k are unit vectors, the dot product a⋅b = a1b1+a2b2+a3b3.

Write a program in c language to store the information of any biological entity in a structure array. Data members in the structure should be of int and char data type with source code. Also includes strings in it. Your program should read the data from user and then store in structure and display in tabular form. Need source code in simple C language.

circumstances. The following program shows this approach: // Use a generic functional interface with lambda expressions. Comedebane.

Write a program to code text editor. Note: Use DSA C++ Language. The goal of this program is to implementing and using stacks and linked structures. You should also continue to use object-oriented design.For this program, you will implement a text editor. Your editor will display a string of characters and a cursor. Your program will allow the user to move the cursor and modify the text using the following five operations: left - move the cursor to the left one character or do nothing if at the end of the line right - move the cursor to the right one character or do nothing if at the end of the line rdelete n - delete n characters to the right of the cursor ldelete n - delete n characters to the left of the cursor insert c - insert the character c just before the cursor

Please implement the follwoing problem in C++: Implement a symbol balance checker function for the Pascal programming language.  Pascal allows for the following pairs: {}, (), [], begin end .  All programs will begin with the word "begin" and end  with the word "end".  Your function should receive an ifstream object which is already open and will return true, all of the symbols match, or false, they do not.  You do not have to worry about comments in the program but you do have to avoid other parts of the program's code such as assignment statements (x=y) and other expressions.

Write the function f(x,y) = x2 + 6xy + 9y2 using lambda abstraction. How to represent the redex if you put the value of x equals to 4 and y equal to -1. Evaluate the function using lambda calculus.

Data structures are defined as: What does the term "abstract data type" refer to? Could you elucidate your response with an example?

Python 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.

Please help me with this! Develop a high-quality, menu-driven object-oriented C++ program that creates a small database, using a binary search tree structure to store and process the data.  The database will contain the top 100 highest grossing films of 2017.   The C++ object-oriented program must use the BinarySearchTree class . When designing and implementing the program, apply good software engineering principles. Start the analysis and design process by drawing a complete UML class diagram for the program that includes all the classes that are contained in the program, including the classes provided by the textbook and the classes that you create.  The UML class diagram will assist you in understanding the components of the project. Your program must include: a Film class that stores all the data for a Film and provides appropriate methods to support good software engineering principles, a FilmDatabase class that stores the binary search tree and provides appropriate methods in…

Question No.1: You are supposed to implement lexer (lexical Analysis). Role of lexer is to remove extra spaces, comments from given code. It completely scans the code and generates tokens from source code. You are supposed to implement lexer to generate token list. C++ language has following tokens. Keywords Identifiers Constants • Strings • Operator You can use C++ language for implementation Note: Paste C++ Code and demo screen shots.

Write a C++ program that simulates a two-dimensional random walk along a grid that has M by N function parameters.The walker moves in one of four directions. The walker chooses the direction randomly. The walker cannot move off the grid. The function ends when the walker visits every grid position at least once. The function returns a dynamic structure that is an ordered record of the walker's positions over time. The first element of the structure is the walker's first position. The last element is the walker's last position.

Study the Java BNF to ensure that you understand the notational conventions used in that BNF. Now, use those notational conventions to write a concise rule to capture the following syntax. That is, write BNF rules that could be added to the given BNF  <zero or more comma separated identifiers> <one or more space separated identifiers>

How is data binding affected when working with immutable data structures?

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…

Problem D. Find URLsHTML is a language for representing documents designed to be displayed by a web browser. In many browsers, you can see the HTML source code by right-clicking somewhere on the page and clicking “View Page Source”. If you try this on a web page with links to other websites, you’ll notice that the URL of the link is usually formatted in the following way: href="https://some.website.com/subfolder/more_stuff.txt" Write a function find_url(html) that takes in a string of html text that contains exactly one external link URL formatted as above, and returns just the URL string (in the above example, that would be https://some.website.com/subfolder/more_stuff.txt). You can assume that the only place in the string where the substring href=" occurs is right before the URL, and that the next quotation mark after that point denotes the end of the URL. Hints: ●  The .find method and string slicing will likely make this easier. ●  Remember that in order to use a double quote…
