Program Plan Intro

Stack:

  • A Stack is data structure, in which element can be inserted and deleted at the same end called top of stack.
  • Stack is open at only one end.
  • Stack is working based on the “Last-In-First-Out (LIFO)” structure.
  • An element that is inserted last always can be deleted first from top of the Stack.

Doubly Ended Queue (Deque):

  • A data structure, in which insertion and deletion operations can be done at both the ends, is called Deque.
  • It is a generalized version of Queue data structure, which permits the operations of insertion and deletion at both ends of the Queue.
  • The above statement defines that the element can be inserted at both the front and rear end and also an element can be removed from both the front and rear end.
