Can we remove an element in a single linked list without
traversing?
Lets suppose the link list is like this
1 2 3 4 5 6
We need to remove 4 from this list (without traversing from
beginning) and the final link list shud be 1 2 3 5 6
only thing we know is the pointer to element "4". How can
we remove "4" and link "3" to "5"?

Answer / pradeep
its possible only if it is a doubly linked list.

Memory address of all elements in a linked list are not
continuous. So if we only know the memory address of the
element "4", we cannot know memory address of element "3"
and "5" without traversing. And we cannot remove it from the
linked list.
