Two Consecutive Even or Odd Values

Write a C# Sharp program to check a given array of integers. Return true if the given array contains 2 even or 2 odd values all next to each other.

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 different integer arrays as arguments
            Console.WriteLine(test(new[] { 3, 5, 1, 3, 7 })); // Testing the method with an array that satisfies the condition
            Console.WriteLine(test(new[] { 1, 2, 3, 4 })); // Testing the method with an array that doesn't satisfy the condition
            Console.WriteLine(test(new[] { 3, 3, 5, 5, 5, 5 })); // Testing the method with an array that satisfies the condition with multiple occurrences
            Console.WriteLine(test(new[] { 2, 4, 5, 6 })); // Testing the method with an array that doesn't satisfy the condition
        }           

        // Method to check if an array contains consecutive occurrences of two odd or two even numbers
        static bool test(int[] numbers)
        {
            int tot_odd = 0, tot_even = 0; // Variables to count the consecutive odd and even numbers encountered

            for (int i = 0; i < numbers.Length; i++) // Looping through the elements of the array
            {
                if (tot_odd < 2 && tot_even < 2) // Checking if the total count of consecutive odd and even numbers is less than 2
                {
                    if (numbers[i] % 2 == 0) // If the number is even
                    {
                        tot_even++; // Increment the count of consecutive even numbers
                        tot_odd = 0; // Reset the count of consecutive odd numbers
                    }
                    else // If the number is odd
                    {
                        tot_odd++; // Increment the count of consecutive odd numbers
                        tot_even = 0; // Reset the count of consecutive even numbers
                    }
                }
            }

            // Return true if there are two consecutive odds or two consecutive evens, otherwise false
            return tot_odd == 2 || tot_even == 2;
         }    
   } 
}

Sample Output:

True
False
True
True

Previous: Write a C# Sharp program to check a given array of integers and return true if there is a 3 with a 5 somewhere later in the given array.
Next: Check a given array of integers and return true if the value 5 appears 5 times and there are no 5 next to each other.
