### Scheme Procedure for Element Switching in a List**Objective:** Write a Scheme procedure that takes a list and returns the list created by switching successive elements in the list.**Task Description:**For example, given the list `'(a b c d e f g)` as input, the procedure should produce the list `(b a d c f e g)` as output.**Example:**- **Input List:** `(a b c d e f g)`- **Output List:** `(b a d c f e g)`**Steps to Implement:**1. Define a Scheme procedure to process list elements.2. Switch successive elements within the list.3. Handle cases where the list has an odd number of elements (last element remains in place).**Procedure Example:**```scheme(define (switch-successive-elements lst) (cond [(or (empty? lst) (empty? (rest lst))) lst] ; if list is empty or has only one element, return it [else (cons (second lst) (cons (first lst) (switch-successive-elements (rest (rest lst)))))])); Usage example:(switch-successive-elements '(a b c d e f g)); Returns: (b a d c f e g)```**Manual Tracing of Procedure:**1. **Initial List:** `(a b c d e f g)`2. **First Step:** `b` and `a` are switched: => `(b a)`3. **Remaining List:** `(c d e f g)`4. **Second Step:** `d` and `c` are switched: => `(d c)`5. **Remaining List:** `(e f g)`6. **Third Step:** `f` and `e` are switched: => `(f e)`7. **Remaining List:** `(g)`8. **Final Step:** `g` remains as it is.So, the final output list is `(b a d c f e g)`.**Study Tip:**Please study provided examples in the lecture notes to learn how to manually trace our procedure. Manually tracing helps understand the recursion and list processing techniques in Scheme.This procedure is helpful in understanding basic list manipulation and recursion concepts in functional programming using Scheme.

6-Write a Scheme procedure that takes a list and returns the list created by switching successive elements in the list. For example (newlist '(a (b) c (de) fg)) returns ((b) a (e d) c gf).Then, Manually trace your procedure with the pro- vided example. Please study provided examples in the lecture notes to learn how you should manually trace our procedure.

Sum Lists' in Scheme; Write a function named sum-lists in Scheme that takes two lists as input and returns a new list containing the sum of each corresponding pair of elements. You may assume that the lists have the same length. For example, (sum-lists '(1 2 3 4) '(5 6 7 8)) should return '(6 8 10 12) (every-other '() '()) should return '()

LINKED LIST IMPLEMENTATION Subject: Data Structure and Algorithm in C++Create a Student Record Management system that can perform the following operations:1) Insert student records2) Delete student record3) Show student record4) Search student record The student record should contain the following items1) Name of Student2) Student Matriculation ID number3) Course in which the student is enrolled4) Total marks of the student Approach: With the basic knowledge of operations of Linked Lists like insertion, deletion of elements in linked list, the student record management can be created. Below are the functionalities explained that are to be implemented.●Check Record: It is a utility function of creating a record it checks before insertion that the Record Already exist or not. It uses the concept of checking for a Node with given Data in a linked list.-Create Record: It is as simple as creating a new node in the Empty Linked list or inserting a new node in a non-Empty linked list.-Search…
