Chapter 20, Problem 20RQE

Program Plan Intro

Binary tree:

It is a tree data structure which comes under hierarchical data structure.

It is made of nodes that have a left child, right child and a data element.

Tree traversal:

There are 3 common methods

Inorder traversal

Preorder traversal

Postorder traversal

In inorder traversal, the left subtree is encountered first, then data node and then the right subtree.

In preorder traversal, the data node is encountered first, then left subtree and then the right subtree.

In postorder traversal, the left subtree is encountered first, then right subtree and then the data node.

Algorithm for Postorder traversal:

Traverse through the leftmost subtree and then print the element.

Ttraverse the rightmost subtree and then print the element.

At last visit and print the root node.

A cylinder of diameter 10 cm rotates concentrically inside another hollow cylinder of inner diameter 10.1 cm. Both cylinders are 20 cm long and stand with their axis vertical. The annular space is filled with oil. If a torque of 100 kg cm is required to rotate the inner cylinder at 100 rpm, determine the viscosity of oil. Ans. μ= 29.82poise

Make the following game user friendly with GUI, with some simple graphics The following code works as this: The objective of the player is to escape from this labyrinth. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units. Cell Class: public class Cell { private boolean isWall; public Cell(boolean isWall) { this.isWall = isWall; } public boolean isWall() { return isWall; } public void setWall(boolean isWall) { this.isWall = isWall; } @Override public String toString() {…
