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"?

1) copy content of element 5 to element 4
2) link element 4(which already contains number 5) to
element 6
3) delete element 5

on.....at last delete the last node r set it to null

Answer / codeg
it is not possible in Single AND double linked list without
traversing from first and not knowing addr of 4..
its possible in circular doubly linked list only........

Answer / pradeep
its possible only if it is a doubly linked list.
| Is This Answer Correct ? | 3 Yes | 6 No |
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.

class Alpha { public: char data[10000]; Alpha(); ~Alpha(); }; class Beta { public: Beta() { n = 0; } void FillData(Alpha a); private: int n; }; How do you make the above sample code more efficient? a) If possible, make the constructor for Beta private to reduce the overhead of public constructors. b) Change the return type in FillData to int to negate the implicit return conversion from "int" to "void". c) Make the destructor for Alpha virtual. d) Make the constructor for Alpha virtual. e) Pass a const reference to Alpha in FillData
