C#: Find the pair of adjacent elements that has the largest product of an given array which is equal to a given value

C# Sharp Basic: Exercise-55 with Solution

Max Product of Adjacent Elements

Write a C# program to find the pair of adjacent elements that has the largest product of the given array.

Sample Solution:

C# Sharp Code:

using System;

public class Exercise
{
    // Function to calculate the maximum product of adjacent elements in an array
    public static int array_adjacent_elements_product(int[] input_array)
    {
        // Initializing variables
        int array_index = 0;

        // Calculating the product of the first two elements in the array
        int product = input_array[array_index] * input_array[array_index + 1];

        // Moving to the next element in the array
        array_index++;

        // Loop to calculate the maximum product of adjacent elements
        while (array_index + 1 < input_array.Length)
        {
            // Checking if the product of the current adjacent elements is greater than the existing product
            product = ((input_array[array_index] * input_array[array_index + 1]) > product) ?
                       (input_array[array_index] * input_array[array_index + 1]) :
                        product;

            // Moving to the next pair of adjacent elements in the array
            array_index++;
        }

        // Returning the maximum product of adjacent elements in the array
        return product;
    }

    // Main method to test the array_adjacent_elements_product function
    public static void Main()
    {
        // Testing the function with sample input arrays and comparing the results
        Console.WriteLine(array_adjacent_elements_product(new int[] { 2, 4, 2, 6, 9, 3 }) == 27);
        Console.WriteLine(array_adjacent_elements_product(new int[] { 0, -1, -1, -2 }) == 2);
        Console.WriteLine(array_adjacent_elements_product(new int[] { 6, 1, 12, 3, 1, 4 }) == 36);
        Console.WriteLine(array_adjacent_elements_product(new int[] { 1, 4, 3, 0 }) == 16);
    }
}

Sample Output:

False
True
True
False
