Answer:
A Red Black Tree is a type of self-balancing(BST) in this tree ,each node is red or black colored. The red black tree meets all the properties of the binary search tree, but some additional properties have been added to a Red Black Tree.
A Red-Black tree's height is O(Logn) where (n is the tree's amount of nodes).
In a red-black tree with black height k
The maximum number of internal nodes is 
.
The smallest possible number is 
.
<span>The network topology describes the physical arrangement, installation, and connection of cables, computer, and other devices.
The network topology can be bus topology (a</span><span> network topology that uses a single cable or conductor to connect all nodes on the network.) ,</span>star topology (a network topology in which cables running from each node connect to a single point, such as a hub.), ring (a network topology that consists of a single cable that runs continuously from node to node), mesh, hybrid, hub topology,... according the arrangement of the nodes.
Answer:
The output of the given code as follows:
Output:
Area is: 12.60676
Explanation:
In the given code some information is missing so, the correct code to this question can be described as follows:
Program:
public class Test //defining class
{
public static void main(String[] args)//defining the main method
{
double radius= 2; //defining double variable radius
final double PI= 3.15169; //defining double variable PI
double area = radius * radius * PI; //defining double variable area that calculates values
System.out.println("Area is: " + area); //print values
}
}
Explanation:
- In the given java code a class "Test" is defined, in which a double variable "radius" is defined, which holds a value, that is 2.
- In the next step, a double constant variable, that is PI is defined, that holds a value, that is "3.15169".
- Then another double variable area is defined, that calculates the area value, and prints its value.
