C#: Find the largest value from first, last, and middle elements of a given array of integers of odd length (at least 1)

C# Sharp Basic Algorithm: Exercise-107 with Solution

Largest Among First, Middle, and Last Elements

Write a C# Sharp program to find the largest value from first, last, and middle elements of a given array of integers of odd length (at least 1).

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
        {          
            // Outputting the result of the 'test' method with various integer arrays as arguments
            Console.WriteLine(test(new[] {1}));
            Console.WriteLine(test(new[] {1,2,9}));
            Console.WriteLine(test(new[] {1,2,9,3,3}));
            Console.WriteLine(test(new[] {1,2,3,4,5,6,7}));
            Console.WriteLine(test(new[] {1,2,2,3,7,8,9,10,6,5,4}));
        }        

        // Method to find and return the maximum value among the first, middle, and last elements of an array
        static int test(int[] numbers)
        {
            // Variables to store the first, middle, last, and maximum elements of the input array
            int first, middle_ele, last_ele, max_ele;

            // Storing the values of the first, middle, and last elements in respective variables
            first = numbers[0];
            middle_ele = numbers[numbers.Length / 2];
            last_ele = numbers[numbers.Length - 1];
            max_ele = first; // Assuming the maximum element is initially the first element

            // Checking if the middle element is greater than the current maximum element
            if (middle_ele > max_ele)
            {
                max_ele = middle_ele; // Updating the maximum element if the middle element is larger
            }

            // Checking if the last element is greater than the current maximum element
            if (last_ele > max_ele)
            {
                max_ele = last_ele; // Updating the maximum element if the last element is larger
            }

            return max_ele; // Returning the maximum element found among first, middle, and last elements
        }
   }
}

Sample Output:

Previous: Write a C# Sharp program to create a new array length 4 from a given array (length atleast 4) containing the elements from the middle of the array.
Next: Write a C# Sharp program to create a new array taking the first two elements from a given array. If the length of the given array is less than 2 then return the give array.
