Please elaborate on the distinction between the bound and unbounded stack.
Please explain the distinction between the restricted version of the stack and the unlimited version of the stack.
In Go Lang 4. Program stack. For the following code, answer the following questions. Assume we are putting everything for our function calls on the stack. · Show what a stack frame/activation record for main() looks like · Show what the stack frame/activation record for the 2nd call to ctTarg look like? (Yes, this means you can skip the other stack frames) · We note that targ does not change value in any recursive call. Why doesn't the compiler just store targ once in one block of memory big enough to store a string? int ctTarg(string* list, int len, string targ) { if (len <= 0) return 0; if (*list == targ) return 1 + ctTarg(list + 1, len - 1, targ); return ctTarg(list + 1, len - 1, targ); } int main() { string pets[] = {"cat", "dog", "mouse", "cat"}; cout << ctTarg(pets, 4, "cat") << endl; }
Project Overview: This project is for testing the use and understanding of stacks. In this assignment, you will be writing a program that reads in a stream of text and tests for mismatched delimiters. First, you will create a stack class that stores, in each node, a character (char), a line number (int) and a character count (int). This can either be based on a dynamic stack or a static stack from the book, modified according to these requirements. I suggest using a stack of structs that have the char, line number and character count as members, but you can do this separately if you wish.Second, your program should start reading in lines of text from the user. This reading in of lines of text (using getline) should only end when it receives the line “DONE”.While the text is being read, you will use this stack to test for matching “blocks”. That is, the text coming in will have the delimiters to bracket information into blocks, the braces {}, parentheses (), and brackets [ ]. A string…
TRUE or FALSE? Answer the following question and state the reason why: cout<<list.back()<<endl; = The back member function returns a reference to the last element in the list. In a Dynamic Stack, the pointer top stays at the head after a push operation. During a Pop operation in Static Stack, the elements are being moved one step up. In a dynamic implementation of stack, the pointer top has an initial value of null.
TRUE or FALSE? Answer the following question and state the reason why: A circular linked list has 2 node pointers. cout<<list.back()<<endl; = The back member function returns a reference to the last element in the list. In a Dynamic Stack, the pointer top stays at the head after a push operation. During a Pop operation in Static Stack, the elements are being moved one step up. In a dynamic implementation of stack, the pointer top has an initial value of null.
Assume the function: void F(stack<T> &S){ } and we send a stack S to the function F, as a result of it إختر أحد الخيارات: a. Both (copy constructor and destructor) should be called b.

4. Sort elements in an array-based stack in ascending order, i.e. make the smallest element to be the top element of the stack. E.g. given the stack elements (from bottom to top): 90, 70, 80, 10, sort the elements to make the stack elements become (from bottom to top): 90, 80, 70, 10. The only data structure you can use is array-based stack. In addition to the given stack, you can use only one extra stack to store some temporary data. Given a stack st, use one extra stack, tmpst, to store temporary data. Here are some hints of the idea. Pop out the top element of st to a variable tmp. If the stack tmpst is empty, push tmp onto tmpst; if tmpst is not empty, pop out its top element and push that element onto st until the top element of tmpst is smaller than tmp, then push tmp onto tmpst .. a. Write a program to implement the stack based sorting. b. Take the input (90, 70, 80, 10) as an example. c. Print all the push and pop operations in proper format. d. At the end, print the sorted…
Select the statements that apply to the use of the frame pointer. EBP is often called the base pointer or frame pointer because it holds the base address of the stack frame. EBP does not changes value during the procedure. EBP need not be restored to its original value when a procedure returns. A procedure can explicitly access stack parameters using constant offsets from EBP.
Develop an application using java language that store characters A, B and C in a stack array and then displays both the size and the last-in element of the stack. The application should then remove the last element of the stack and then display again both the size and the last-in element of the stack. Appropriate stack methods should be used to add, delete and display characters.
Consider the Stack ADT: Stack: push(x) adds x to top of stack pop() removes top element of stack and returns it size() returns number of elements in stack Select all options that allow for an efficient implementation based on the discussions from class. For any array implementation, you can assume the array is large enough so that making a larger one is not needed when pushing an item to the stack. Using an array with the top at the front of the array. Using an array with the top at the back of the array. Using a singly linked list with the top at the head of the list. Using a singly linked list with the top at the tail of the list. ENG
A- Declare a self-referential structure for a linked list having one data StudentNode field called GPA (float), and one pointer to StudentNode called next. B- Write a non-recursive function - that counts all the GPAS that are less than or equal to 2 in your linked list starting from the head of the list. Example: If the list is 1.9->2->3.5->4->1.8, the function should return 3. C- Write a recursive function that prints all the GPAS that are higher or equal to 3.5 in your linked list starting from the head of the list. Example: If the list is 1.9->2->3.5->4->1.8, the function should print: 3.5->4.
