Implement the following function. You may use the stack template class and the stack operations of push, pop, peek, is_empty, and size. You may also use cin.peek( ) and use "cin>>i" to read an integer. int evaluate_postfix_from_cin() // Precondition (Which is not checked) : The next input line of cin is a // properly formed postfix expression consisting of integers, // the binary operations + and -, and spaces. // Postcondition: The function has read the next input line (including // the newline) and returned the value of the postfix expression. int i; stack s;

Write in C++ Sam is making a list of his favorite Pokemon. However, he changes his mind a lot. Help Sam write a function insertAfter() that takes five parameters and inserts the name of a Pokemon right after a specific index. Function specifications Name: insertAfter() Parameters (Your function should accept these parameters IN THIS ORDER): input_strings string: The array containing strings num_elements int: The number of elements that are currently stored in the array arr_size int: The number of elements that can be stored in the array index int: The location to insert a new string. Note that the new string should be inserted after this location. string_to_insert string: The new string to be inserted into the array Return Value: bool: true: If the string is successfully inserted into the array false: If the array is full If the index value exceeds the size of the array
C++ in visual studio: Implement it completely with copy constructor, overloaded assignment operator and destructor. Then, in main, type an application that creates 2 numbers, sums them, and assigns the result to a new number. for example ; Number 1 (18,32) Number 2 (15.09) - - - - - - - - - - - + Number 3 ( 33,41)
TRUE OR FALSE 1. One disadvantage of Boolean type is readability 2. When string length is specified at the declaration time then we call it Static Length 3. In stack-dynamic array subscript ranges are dynamically bound 4. Access to record elements is slower than access to array 5. It is possible to check type (type checking) when using free union

Implement the following function using C++ remove_redundant() This method will clear out the duplicate numbers in your linked list. It is also imperative that you will use an instance of this Linked List class to hold the numbers that you have already checked and use the methods in this instance. In the example 10 -> 10 -> 20 -> 30 -> 10, calling remove_redundant() will remove the other 2 10's that occurred later, hereby making the list 10 -> 20 -> 30. Limitation: You cannot have a nested loop here nor use methods that employ loops as the performance of our linked list will suffer.
If the elements “A”, “B”, “C” and “D” are placed in a stack and are removed one at a time, in what order will they be removed?
Use Clojure: a. The built-in function type is useful for checking what kind of object an expression evaluates to. Write a function both-same-type? that takes two arguments, and returns true when they both have the same type, and false otherwise. b. Write a function list-longer-than? which takes two arguments: an integer n, and a list lst and returns true if lst has more than n elements, and false otherwise. For example, (list-longer-than? 3 '(1 2 3)) should return false, and (list-longer-than? 2 '(1 2 3)) should return true.

JAVA CODE Learning Objectives: Detailed understanding of the linked list and its implementation. Practice with inorder sorting. Practice with use of Java exceptions. Practice use of generics. You have been provided with java code for SomeList<T> class. This code is for a general linked list implementation where the elements are not ordered. For this assignment you will modify the code provided to create a SortedList<T> class that will maintain elements in a linked list in ascending order and allow the removal of objects from both the front and back. You will be required to add methods for inserting an object in order (InsertInorder) and removing an object from the front or back. You will write a test program, ListTest, that inserts 25 random integers, between 0 and 100, into the linked list resulting in an in-order list. Your code to remove an object must include the exception NoSuchElementException. Demonstrate your code by displaying the ordered linked list and…
