  4. Convert a Singly Linked List to an array - GeeksforGeeks

    Sep 4, 2024 · Given a singly linked list and the task is to convert it into an array. Examples: Input: List = 1 -> 2 -> 3 -> 4 -> NULL Output: 1 2 3 4. Input: List = 10 -> 20 -> 30 -> 40 -> 50 -> NULL Output: 10 20 30 40 50 . Approach: The idea is to iterate through the linked list and for each node add its value into the array. C++

  5. Convert List to Linked List & Vice-Versa in Python (2 Examples)

  10. Python: Converting a linked list to a list using a list

    Feb 20, 2019 · Let's say I have a simple linked list implementation using a dictionary called child that associates a node with the following node in the linked list. For example: a->b->c->d Would be : {a:b,b:c,c:d,d:None} Converting this to a normal list is trivial, myList=[] node=a while node!=None: myList.append(node) node=child[node]
