- Please organise your work. Thank You 1. Convert the following from infix to prefix using stacks:(5 – y) * (x + 3) 2. Convert the following from postfix to prefix using stacks:a b c + - d *S1 and S2 are two sorted stacks of n and m numbers, with the top elements of each stack pointing to the smallest number in their list. To ensure that all of the components in stacks S1 and S2 are available in MERGE in decreasing order, with the largest element at the top, create a stack MERGE that combines the items in stacks S1 and S2.Remember that there are (n + m) components in the stack MERGE.You must use stacks to do the following conversions. 1. Convert the following from infix to prefix using stacks:(5 – y) * (x + 3) 2. Convert the following from postfix to prefix using stacks:a b c + - d * 3. Evaluate the postfix expression using stacks.7 4 -3 * 1 5 + / * 4. Convert the following from postfix to infix using stacks:a b c - + d e - f g - h + / *

- q15) Which of the following structure is used to implement dynamic stack? a. Structures b. Linked List c. Unions d. ArraysQ: Write the code in c++ of Stack By Link List and Perform MultipleTask which are given below. Add all the given tasks in the code 1. Push value in stack2. Check that Stack is Empty or Not.3. POP values From Stack.4. Search any values from stack.5. Update any value from stack. NOTE: STACK BY LINKLISTWrite a program in C to insert or delete characters in a buffer. You need to use stack operations to maintain operations for a buffer in a text editor. The program implements the following operations using two stacks that are represented using linked list: Create an empty buffer createBuffer() Insert a character at the cursor position insert() Get the character at the cursor position char get() Delete and return the character at the cursor char delete() Move the cursor k position to the left void left (int k) Move the cursor k positions to the right void right(int k) Requirements: You need to implement the Stack ADT using either Array or Linked list implementation for the following operations in a file named “stack.h”: Stack initialize() boolean IsEmpty (Stack) character pop (Stack) Stack push(Stack and character) character top (Stack) size(Stack) The driver program interface can be either menu-based driven application that displays…
- What does this code accomplish? lw $4,0($sp)lw $3,4($sp)0addi $sp,$sp,8 a push the contents of $4, then $3, onto stack b pop from stack into $4, then pop from stack into $3 c pop from stack into $3, then pop from stack into $4 d push the contents of $3, then $4, onto stack54. What is the difference between the top and pop operations of a stack? Group of answer choices The top operation removes the top item of the stack. The pop operation returns a reference to the top item on the stack and remove it. The top operation removes the top item of the stack. The pop operation returns a reference to the top item on the stack without removing it. The pop operation removes the top item of the stack. The top operation returns a reference to the top item on the stack without removing it. The pop and top operations are doing the same thing which removes the top item of the stack. The pop operation removes the top item of the stack. The top operation returns a reference to the top item on the stack and remove it.q5) Which of the following is not true about stack data structure? a. Stack is data structure which stores data in last in first out method. b. Stack is a logical structure defined in the main memory. c. Stack can be implemented by arrays and linked list. d. Stack is a data structure which stores data in first in first out method.
