Suppose we want to write a loop that traverses a doubly-linked circular linked list. Assume that each node has a prev and a next reference, and the list itself maintains a reference to a head node. What is wrong with this loop header?
for (Node curr = head; curr != head.prev; curr = curr.next)
What will be an ideal response?
It will stop just short of the last node.
