In this article, we will be solving HackerRank Day 0: Hello, World problem, part of 30 Days of Code. Majorly, we will use Python3 and Java15 to solve the problem.

Objective

In this challenge, we review some basic concepts that will get you started with this series. You will need to use the same (or similar) syntax to read input and write output in challenges throughout HackerRank. Check out the Tutorial tab for learning materials and an instructional video!

Task

Print Hello, World. on the first line, and on the second line, we print the content of the input_string variable.

Input Format

A single line of text denoting input_string (the variable whose contents must be printed).

Output Format

Print Hello, World. on the first line, and the contents of input_string on the second line.

Solution Day 0: Hello, World in Python3

# Read a full line of input from stdin and save it to our dynamically typed variable, input_string.
input_string = input()

# Print a string literal saying "Hello, World." to stdout.
print('Hello, World.')
print(input_string)

# TODO: Write a line of code here that prints the contents of input_string to stdout.

Solution Day 0: Hello, World in Java15

import java.io.*;
import java.util.*;

public class Solution {

    public static void main(String[] args) {
        System.out.println("Hello, World.");
        Scanner s1 = new Scanner(System.in);
        String s = s1.nextLine();
        
        System.out.println(s);
    }
}
