Question
Given pointer to a node X in a singly linked list. Only one pointer is given, pointer to head node is not given, can we delete the node X from given linked list?Possible if X is not last node. Use following two steps (a) Copy the data of next of X to X. (b) Delete next of X.Possible if size of linked list is even.Possible if size of linked list is oddPossible if X is not first node. Use following two steps (a) Copy the data of next of X to X.
Solution
The deletion of a node X from a singly linked list, given only a pointer to X and not to the head node, is possible if X is not the last node. This can be achieved through the following steps:
(a) Copy the data from the next node of X to X. This essentially overwrites the data in X with the data from the next node.
(b) Delete the next node of X. This effectively removes the next node from the list, and since its data was copied to X, the overall data of the list remains the same.
The size of the linked list (whether it's even or odd) does not affect the ability to delete the node X. Similarly, whether X is the first node or not is irrelevant since we don't have a pointer to the head node. The only condition is that X should not be the last node in the list.
