Hi guyz,
*Given only a pointer to a node to be deleted in a singly linked list, how
do you delete it?*
if that node is in between the list, we can copy the data from next node
into this node and we can delete the next node.
what if the node to be deleted is last node ??
if the list is circular
void delete(node *ptr) {
node *newptr = ptr-next;
ptr-val = newptr-val;
ptr-next = newptr-next;
delete newptr;
}

it wont work.u can set a sentinel value for the last node and make it
dummy.so every time u scan the list u need to compare
while(list != null and list-vlue != dummy)

@sukran: So can't I delete the last node, if pointer to that node is given?
Can you please elaborate it..

@karthik
here u'r just making the pointer null that means pointer reference gets lost
but
?
1-23
here ? means pointer that gets lost if u make it null but the 2 node is
still pointing to 3 , how would u solve dis one.
