Recap - Sigma Function

Coddy'nin Java Journey'sinin Temeller bölümünün bir parçası — ders 55 / 73.

Görev

Kolay

sigma adında, bir sayı olan n'yi temsil eden tek bir argüman alan bir fonksiyon yazın.

Fonksiyon, 1'den n'ye kadar olan (dahil) tüm sayıların toplamını return edecektir.

Örneğin, sigma(5) için fonksiyon 15 döndürecektir, çünkü 15 = 1 + 2 + 3 + 4 + 5.

Kendin dene

import java.util.Scanner;

public class Main {
    public static int sigma(int n) {
        // Kodunuzu aşağıya yazın
    }
    
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int n = scanner.nextInt();
        int res = sigma(n);
        System.out.println(res);
    }
}
