Problem: List Reverse in JavaScript Given a list: var list = { value: 1, next: { value: 2, next: { value: 3, next: null } } }; Reverse the order of the list so that it looks like: var list = { value: 3, next: { value: 2, next: { value: 1, next: null } } }; Use the following shell if needed: function reverseList(list) { // your code here ... return reversedList; } Example Test Case(s): Arguments: { value: 1, next: { value: 2, next: { value: 3, next: null } } }; Returns: { value: 3, next: { value: 2, next: { value: 1, next: null } } }; Arguments: { value: "a", next: { value: "b", next: { value: "c", next: null } } }; Returns: { value: "c", next: { value: "b", next: { value: "a", next: null } } }; Requirements: You cannot use the built-in reverse() function. null is non-existent object, you may use an empty object instead if desired. Your function should be able to reverse a list of values of any type. You must use at least one array to solve the problem. Hints: Try breaking down the problem into multiple functions based on the exercises from the textbook code sandbox problems. The following would potentially be the functions in your program: Turn the list into an array -> listToArray(...) Reverse the array -> reverseArray(...) Turn the array into a list -> arrayToList(...)

Problem: List Reverse in JavaScript

Given a list:

var list = { value: 1, next: { value: 2, next: { value: 3, next: null
} } };

Reverse the order of the list so that it looks like:

var list = { value: 3, next: { value: 2, next: { value: 1, next: null } } };

Use the following shell if needed:

Requirements:

You cannot use the built-in reverse() function.
null is non-existent object, you may use an empty object instead if desired.
Your function should be able to reverse a list of values of any type.
You must use at least one array to solve the problem.

Hints:

Try breaking down the problem into multiple functions based on the exercises from the textbook code sandbox problems. The following would potentially be the functions in your program:
- Turn the list into an array -> listToArray(...)
- Reverse the array -> reverseArray(...)
- Turn the array into a list -> arrayToList(...)
