Hi, look at the image below and confirm that it is a doubly linked list. I thought a doubly linked list has two arrows for each node (one arrow pointing forward and the second arrow pointing backward). However, the example of the double linked list below was given by my instructor. I'm not sure if that is correct. Please explain.

In a doubly linked list, each element points to its successor and to its predecessor; a list item stores an element and two pointers, one to its successor and one to its predecessor ItemItemItem 3 Item FIRST1 4 2
