Hackerrank - Project Euler+ #013 - Large sum

Hackerrank – Problem description

The problem description – Hackerrank.

Solution

We need to sum all given numbers. The catch is to use a feature of chosen programming language, which allows us operation with big numbers (e. g. BigInteger in Java)

I created solution in:

Java

All solutions are also available on my GitHub profile.

Java

import java.math.BigInteger;
import java.util.Scanner;

public class LargeSum
{
	public static void main(String[] args)
	{
		Scanner scanner = new Scanner(System.in);
		int numbers = Integer.parseInt(scanner.nextLine());
		BigInteger sum = BigInteger.ZERO;
		for (int i = 0; i < numbers; i++)
		{
			String input = scanner.nextLine();
			sum = sum.add(new BigInteger(input));
		}
		System.out.println(sum.toString().substring(0, 10));
		scanner.close();
	}
}

import java.math.BigInteger;

import java.util.Scanner;

public class LargeSum

{

public static void main(String[] args)

{

Scanner scanner = new Scanner(System.in);

int numbers = Integer.parseInt(scanner.nextLine());

BigInteger sum = BigInteger.ZERO;

for (int i = 0; i < numbers; i++)

{

String input = scanner.nextLine();

sum = sum.add(new BigInteger(input));

}

System.out.println(sum.toString().substring(0, 10));

scanner.close();

}
