Difference Between Largest and Smallest Values

Write a C# Sharp program to compute the difference between the largest and smallest values in a given array of integers and lengths of one or more.

Visual Presentation:

Sample Solution:-

C# Sharp Code:

using System; // Importing the System namespace

namespace exercises // Defining a namespace called 'exercises'
{
    class Program // Defining a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {       
            // Displaying a message indicating the purpose of the output
            Console.WriteLine("Difference between the largest and smallest values: ");

            // Outputting the result of the 'test' method with an integer array as an argument
            Console.WriteLine(test(new[] { 1, 5, 7, 9, 10, 12 })); 
        }           

        // Method to calculate the difference between the largest and smallest values in the given array
        static int test(int[] nums)
        {
            int small_num = 0, biggest_num = 0; // Initializing variables for the smallest and largest numbers

            // Checking if the array has elements to avoid accessing empty arrays
            if (nums.Length > 0)
            {
                small_num = biggest_num = nums[0]; // Assigning the first element as the initial smallest and largest numbers
            }

            // Looping through the array to find the smallest and largest numbers
            for (int i = 1; i < nums.Length; i++)
            {
                small_num = Math.Min(small_num, nums[i]); // Updating the smallest number found so far
                biggest_num = Math.Max(biggest_num, nums[i]); // Updating the largest number found so far
            }

            return biggest_num - small_num; // Returning the difference between the largest and smallest numbers
        }    
   }
}

Sample Output:

Difference between the largest and smallest values: 
11
