Answer / ujjwal dave

Stack and Queue are also not correct because in stack
elements can be added and deleted only from one end.
In queue addition takes place at one end and deletion from
other.....
we want to add elements at both ends.....so deques is the
only correct answer

Answer / poornakala

linked list is not right. its two way stack. double ended
queue can also cannot be as u need to have 4 pointers for
them... but two way stack needs 2 pointers and can only be
deleted and inserted at the end.

Answer / vaishali naidu

Double ended queue is the right answer but stack and queue
are also right answers as they allow LIFO and FIFO
principles not deletion or inserting from middle. IF its a
priority queue then we can insert the elements in between.

Answer / gopesh

IT is stack...because we can push or pop at one end.......it can be done using array where one side is fixed or using linked list where either head is kept constant or null node.....
