**Welcome to Java!**

### Problem Statement :

Welcome to the world of Java! In this challenge, we practice printing to stdout. The code stubs in your editor declare a Solution class and a main method. Complete the main method by copying the two lines of code below and pasting them inside the body of your main method. System.out.println("Hello, World."); System.out.println("Hello, Java."); Input Format There is no input for this challenge. Output Format You must print two lines of output: Print Hello, World. on the first line. Print Hello, Java. on the second line.

### Solution :

` ````
Solution in C :
public class HelloWorld {
public static void main(String[] args){
System.out.println("Hello World.");
System.out.println("Hello Java.");
}
}

Andy and Lily love playing games with numbers and trees. Today they have a tree consisting of n nodes and n -1 edges. Each edge i has an integer weight, wi. Before the game starts, Andy chooses an unordered pair of distinct nodes, ( u , v ), and uses all the edge weights present on the unique path from node u to node v to construct a list of numbers. For example, in the diagram below, Andy
