In old versions of Fortran that did not have the character data type, character strings wereexpressed in the following format: ::= H where the is a base-ten integer (≥ 1), H is a keyword (named after HermanHollerith), and is a sequence of characters.The semantics of this string literal is correct if the base-ten numeral's numeric value matchesthe string's length.Write an attribute grammar using only synthesized attributes for the nonterminals in the definition.Below is an example of an attribute grammar that defines the meaning of binary numeralsconsisting only of Synthesized Attributes.Base your answer on the example below.Val - stands for the attribute Value.Len - stands for the attribute Length.NonterminalsSynthesizedAttributesInheritedAttributesValVal, LenVal :: , 2Val ()<- Val ()+Val ()/2lm (chinary digitsbinary digits> ::- Val ()2 Val (>2) + Val ()Len () + Len ()+1| Val () Val ()Len ( ::=0Val ()0| 1Val ()1

Can you please help me solve this in C language? I did encounter and solve this problem with Java but I cannot seem to implement the use of structures in solving this problem. Help is appreciated, thank you. Using the concept of structures, write a program to assign passenger seats in an airplane. Assume a small airplane with seats numbered as follows: 1 A B C D 2 A B C D 3 A B C D 4 A B C D 5 A B C D The program should display the seat pattern, marking with an ‘X’ the seats already assigned. For example, after seats 1A, 2B, and 4C are taken, the display should look like: 1 X B C D 2 A X C D 3 A B C D 4 A B X D 5 A B C D Seats are assigned by specifying a number and a letter. If the user types in a seat that is already assigned, the program should say that the seat is occupied and ask for another choice. The program should run until all seats are…

Write a C++ program to read the employee id, employee name, age and salary of 6 employees using array of structures and then find(search) the employee with the highest salary. Also check if a specific employee id is present or not in the array of structure. The program will have: getdata( ):- for reading/getting employee’s id, name and age from the user. SearchID( ) :- for searching if a given employee ID is present or not in the list. HighestSalary( ) :- To find the employee with highest salary and display his name, ID, age and salary Note: All these functions take two arguments i.e.,(Employee e[ ],int size) as arguments.

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.
In this assignment, you will do an implementation of the Huffman Code. If you have the Data Structures book for this class, on pages 415-421 is the theory for encoding a String using the Huffman Code. There is also a PDF of these pages on the class website. Your task is to develop a proof of concept of the Huffman Code and demonstrate it by taking a String and encoding it. The Huffman Code requires knowledge of a few data structure concepts discussed in class: Priority Queues Binary Trees Recursion Arrays and/or Linked Lists In your program, you will demonstrate an understanding of all these concepts by developing your own priority queue, node, binary tree, array and/or linked list, and use of recursion to support the Huffman Code encryption algorithm. Read through the theory of the Huffman Code in the text and then write a program that can take a String and encrypt it. For example, given a String “Hello World”, the program should apply the Huffman Code algorithm on that…
