What the code is about:

Implement a recursive algorithm to add all the elements of a non-dummy headed singly linked linear list. Only head of the list will be given as parameter where you may assume every node can contain only integer as its element. Note: youll need a Singly Node class for this code.

**PLEASE EXPLAIN HOW THE NODE CLASS AND THE CONSTRUCTOR OF THE NODE CLASS IS WORKING IN THIS CODE**

class node: def __init__(self, value = None, next=None): self.value = value self.next = next

def AddAll(head):#takes head of single linked list head if head==None: return 0#if reached end of the linked list return AddAll(head.next) + head.value #each node's next pointer is passed in recursive call #and value of each node is added while returning from recursive call
