O CanvasAssume class StackType has been defined to implement a stack data structure as discussed in your textbook (you may also usethe stack data structure defined in the C++ STL). Write a function that takes a string parameter and determines whether thestring contains balanced parentheses. That is, for each left parenthesis (if there is any) there is exactly one matching rightparenthesis later in the string and every right parenthesis is preceded by exactly one matching left parenthesis earlier in thestring.e.g. abc(c(x)d(e))jh is balanced whereas abc)cd(e)(jh is not.The function algorithm must use a stack data structure to determine whether the string parameter satisfies the conditiondescribed above.EditFormat TableParagraph v|BIUA e Tv|||12pt vWPO words10 pts:::

3.Write a generic class called GenericStack<T> that represents a stack structure. A stack structure follow the strategy last-in-first-out, which means that the last element added to the stack, is the first to be taken out. The GenericStack class has the following attributes and methods: --An attribute ArrayList<T> elements which represents the elements of the stack.(All of you refer collection framework for ArrayList. or you can use an array to hold the elements of Stack.)[Refer the following links to have intro on ArrayList: https://www.w3schools.com/java/java_arraylist.asp, https://www.geeksforgeeks.org/arraylist-in-java/] --A constructor that creates the ArrayList or an Array --A method push(T e) which adds the element to the ArrayList<T> or array. --A method pop() which removes the last element of the ArrayList<T> (last element added), if the list is not already empty and returns it. --A method print() which prints the elements of the stack starting from the…
Implement in C Programming 8.18.1: LAB: Simple linked list Given an IntNode struct and the operating functions for a linked list, complete the following functions to extend the functionality of the linked list: IntNode* IntNode_GetNth(IntNode* firstNode, int n)- Return a pointer to the nth node of the list starting at firstNode. void IntNode_PrintList(IntNode* firstNode) - Call IntNode_PrintNodeData() to output values of the list starting at firstNode. Do not add extra space characters in between values. int IntNode_SumList(IntNode* firstNode) - Return the sum of the values of all nodes starting at firstNode. Note: The code for IntNode_Create() provided here differs from the code shown in the book. The given main() performs various actions to test IntNode_GetNth(), IntNode_PrintList(), and IntNode_SumList(). main() reads 5 integers from a user: The number of nodes to be added to a new list The value of the first node of the list An increment between the values of two consecutive…
*IN C++ A handy feature of lists in Python is that you can use negative indices to get at elements starting from the very end. For example, x[-1] returns the last element in x, x[-2] returns the penultimate element, etc. Implement a struct named "PythonicIntVector" in the files "PythonicIntVector.h" and "PythonicIntVector.cpp" that supports the push_back and at methods of a vector of ints. However, be sure to add the functionality of negative indices. Don't forget that the at method still should throw exceptions for invalid indices (just like in Python)!
the Program in C++, Write a program that evaluates a valid postfix expression such as: 6 2 + 5 * 8 4 / -The program should read a postfix expression consisting of digits and operators into a string. Using modified versions of the stack functions implemented earlier in this chapter, the program should scan the expression and evaluate it. The algorithm is as follows: 1-While you have not reached the end of the string, read the expression from left to right. If the current character is a digit, Push its integer value onto the stack (the integer value of a digit character is its value in the computer’s character set minus the value of '0' in the computer’s character set). Otherwise, if the current character is an operator, Pop the two top elements of the stack into variables x and y. Calculate y operator x. Push the result of the calculation onto the stack. 2-When you reach the end of the string, pop the top value of the stack. This is the result of the postfix expression. [Note: In Step…
Please implement the following problem in C++: Although a queue is "best" implemented with a list, it can be implemented with a vector if you take into account the starting position of the queue. For example, if five elements are pushed onto the queue, the start of the queue is at position zero and the end is at position 4. If we, then, pop two elements, the start would be at position 2 and the end at position 4. The two "popped" elements are not really removed from the vector, and that avoids the O(N) time problem for the pop function.Implement a class which uses a vector to store the queue. Be mindful of performance, such that if the queue is empty, the size of the underlying vector is "reset."

Write a Java public static general function which doesn't belong to the Stack class, isGreaterThan that determines if one stack is greater than another stack. If the summation of every other item(starting at the top) from one stack is greater than the summation of every other item(starting at the top) from another, return true, otherwise, return false. After you call this method, both stacks should stay the same as they are called before. Receives: a Stack type argument S1 and another Stack type argument S2 Postcondition: If the summation of every other item (starting at the top) from S1 is greater than the summation of every other item (starting at the top) from S2, return true, otherwise, return false. Both S1 and S2 should stay the same as they are called before. public static boolean isGreaterThan(Stack S1, Stack S2)

Implement all operations of a linked list as member function of this class. • create_node(int); • insert_begin(); • insert_pos(); • insert_last(); • delete_pos(); • sort(); • search(); • update(); • reverse(); • display(); ( Drop coding in words with screenshot of output as well )
