C# Sharp Basic Algorithm: Exercise-126 with Solution

Write a C# Sharp program to check a given array of integers and return true if the array contains three increasing adjacent numbers.

Visual Presentation:

C# Sharp: Basic Algorithm Exercises - Check a given array of integers and return true if the array contains three increasing adjacent numbers.

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 results of the 'test' method with different integer arrays as arguments
            Console.WriteLine(test(new[] { 1, 2, 3, 5, 3, 7 })); // Testing the method with an array
            Console.WriteLine(test(new[] { 3, 7, 5, 5, 3, 7 })); // Testing the method with an array
            Console.WriteLine(test(new[] { 3, 7, 5, 5, 6, 7, 5 })); // Testing the method with an array   
        }               

        // Method to check if there are three consecutive elements in the array
        static bool test(int[] numbers)
        {
            for (int i = 0; i <= numbers.Length - 3; i++) // Loop through the array elements until the third-to-last element
            {
                // Checking if three consecutive elements form a sequence (incrementing by 1)
                if (numbers[i] == numbers[i + 1] - 1 && numbers[i] == numbers[i + 2] - 2)
                {
                    return true; // Return true if a sequence of three consecutive elements is found
                }
            }
            return false; // Return false if no sequence of three consecutive elements is found
        }    
    } 
}

Sample Output:

True
False
True
