C#: Check a given array of integers and return true if the specified number of same elements appears at the start and end of the given array
C# Sharp Basic Algorithm: Exercise-125 with Solution
Write a C# Sharp program to check a given array of integers. Return true if the specified number of same elements appears at the start and end of the given array.

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 and lengths as arguments
Console.WriteLine(test(new[] { 3, 7, 5, 5, 3, 7 }, 2)); // Testing the method with an array and a length
Console.WriteLine(test(new[] { 3, 7, 5, 5, 3, 7 }, 3)); // Testing the method with an array and a length
Console.WriteLine(test(new[] { 3, 7, 5, 5, 3, 7, 5 }, 3)); // Testing the method with an array and a length
}
// Method to check if the first 'len' elements in the array are the same as the last 'len' elements
static bool test(int[] numbers, int len)
{
int arra_size = numbers.Length; // Storing the length of the array
for (int i = 0; i < len; i++) // Looping through the first 'len' elements
{
// Checking if the current element from the beginning and end of the array are different
if (numbers[i] != numbers[arra_size - len + i])
{
return false; // Returning false if any pair of elements are not equal
}
}
return true; // Returning true if all 'len' pairs of elements are equal
}
}
}
Sample Output:
True False True
