Write a function to find the depth of a binary tree.

Answer Posted / ravi

Assuming we start with Level 1, (in Java)

{{{

public class BinaryTreeSearch {

/**
* @param args
*/
public static void main(String[] args) {

BinaryTreeSearch test = new BinaryTreeSearch();
Node root = test.new Node(null, null, "Value");
Node last = root;
Node middle = null;
for (int i = 0; i < 10; i++) {
Node temp = test.new Node(null, null, "Value");
last.setLeft(temp);
last = temp;
if (i == 5)
middle = temp;
}
for (int i = 0; i < 20; i++) {
Node temp = test.new Node(null, null, "Value");
middle.setRight(temp);
middle = temp;
}

for (int i = 0; i < 10; i++) {
Node temp = test.new Node(null, null, "Value");
last.setRight(temp);
last = temp;
}

int depth = depth(root, 0);
System.out.println(depth);
}

private static int depth(Node node, int level) {
if (null == node)
return level;
level++;
int leftLevel = depth(node.getLeft(), level);
int rightLevel = depth(node.getRight(), level);

if (leftLevel > rightLevel) {
return leftLevel;
} else {
return rightLevel;
}
}

public class Node {
Node left = null;
Node right = null;
String strValue = null;

public Node(Node left, Node right, String value) {
this.left = left;
this.right = right;
this.strValue = value;
}

public void setLeft(Node left) {
this.left = left;
}

public void setRight(Node right) {
this.right = right;
}

public void setValue(String value) {
this.strValue = value;
}

public Node getLeft() {
return left;
}

public Node getRight() {
return right;
}
}
}

}}}

A program that will create a movie seat reservation. The program will display the summary seats and its status. The user will be ask what seat no. to be reserved, then it will go back again to the summary to display the updated seat status. If the seat no. is already reserved then it will prompt an error message. And also if the input seat no is out of range then it will also prompt an error message. The program is continuously running. Termination of the program will depends on how the programmer will apply. Sample output: Movie Seats Reservation Summary of Seats: Seat 1: Available Seat 2: Available Seat 3: Available Seat 4: Available Seat 5: Available Enter seat no. (Press 0 to terminate Or the assigned seat capacity) : 1 Movie Seats Reservation Summary of Seats: Seat 1: Reserve Seat 2: Available Seat 3: Available Seat 4: Available Seat 5: Available Enter seat no. (Press 0 to terminate Or the assigned seat capacity) : 6 The Seat no. is out of range! Movie Seats Reservation Summary of Seats: Seat 1: Reserve Seat 2: Available Seat 3: Available Seat 4: Available Seat 5: Available Enter seat no. (Press 0 to terminate Or the assigned seat capacity) : 1 The Seat no. is already reserved! Movie Seats Reservation Summary of Seats: Seat 1: Reserve Seat 2: Available Seat 3: Available Seat 4: Available Seat 5: Available Enter seat no. (Press 0 to terminate Or the assigned seat capacity) : 0 GoodBye... Thank You!!!
