Program Plan Intro

Queue:

  • A linear data structure, in which element can be inserted into one end and deleted from another end is called Queue.
  • Queue is open at both front and rear end.
  • Queue is working based on the “First-In-First-Out (FIFO)” structure.
  • An element can be inserted only at the rear end and can be deleted only at the front end.

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.

Methods (Ch6) - Review 1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java. There are two methods, method #1 which calculates the square root for positive integers, and method #2, which calculates the square root of positive doubles (also works for integers). public class SquareRoot { public static void main(String[] args) { } // implement a loop of your choice here // Method that calculates the square root of integer variables public static double myRoot(int number) { double root; root=number/2; double root old; do { root old root; root (root_old+number/root_old)/2; } while (Math.abs(root_old-root)>1.8E-6); return root; } // Method that calculates the square root of double variables public static double myRoot(double number) { double root; root number/2; double root_old; do { root old root; root (root_old+number/root_old)/2; while (Math.abs (root_old-root)>1.0E-6); return root; } } Program-it-Yourself: In the main method, create a program that…
