C#: Sum of two lowest negative numbers of a given array of integers

Last update on December 20 2024 12:36:46 (UTC/GMT +8 hours)

Write a C# Sharp program to calculate the sum of the two lowest negative numbers in a given array of integers.

An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers,

Sample Solution:-

C# Sharp Code:

using System;
using System.Linq;

namespace exercises
{
    class Program
    {
        static void Main(string[] args)
        {
            // Initializing an array of integers with negative and positive values
            int[] nums = { -10, -11, -12, -13, -14, 15, 16, 17, 18, 19, 20 };

            // Displaying original array elements
            Console.WriteLine("Original array elements:");
            for (int i = 0; i < nums.Length; i++)
            {
                Console.Write(nums[i] + " ");
            }

            // Finding and displaying the sum of the two lowest negative numbers in the array
            Console.WriteLine("\nSum of two lowest negative numbers of the said array of integers: " + test(nums));

            // Creating another array with both negative and non-negative integers
            int[] nums1 = { -1, -2, -4, 0, 3, 4 , 5, 9 };
            Console.WriteLine("\nOriginal array elements:");
            for (int i = 0; i < nums1.Length; i++)
            {
                Console.Write(nums1[i] + " ");
            }

            // Finding and displaying the sum of the two lowest negative numbers in the second array
            Console.WriteLine("\nSum of two lowest negative numbers of the said array of integers: " + test(nums1));
        }

        // Method to find the sum of the two lowest negative numbers in an array
        public static int test(int[] values)
        {
            // Using LINQ to filter negative numbers, sort them, take the two lowest values, and calculate their sum
            return values.Where(x => x < 0).OrderBy(x => x).Take(2).Sum();
        }
    }
}

Sample Output:

Original array elements:
-10 -11 -12 -13 -14 15 16 17 18 19 20 
Sum of two lowest negative numbers of the said array of integers: -27

Original array elements:
-1 -2 -4 0 3 4 5 9 
Sum of two lowest negative numbers of the said array of integers: -6
