# C#: Check a given array of integers of length 1 or more and return true if the first element and the last element are equal in the given array

## C# Sharp Basic Algorithm: Exercise-89 with Solution

Write a C# Sharp program to check a given array of integers of length 1 or more. Return true if the first and the last element in the array are equal.

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
{
// Output the results of the 'test' function with different integer arrays as arguments
Console.WriteLine(test(new[] { 10, 20, 40, 50 })); // Calling test method with array [10, 20, 40, 50] and displaying the result
Console.WriteLine(test(new[] { 10, 20, 40, 10 })); // Calling test method with array [10, 20, 40, 10] and displaying the result
Console.WriteLine(test(new[] { 12, 24, 35, 55 })); // Calling test method with array [12, 24, 35, 55] and displaying the result

Console.ReadLine(); // Waiting for user input before closing the console window
}

// Method to check if the first and last elements of an array are equal
public static bool test(int[] nums)
{
// Returns true if the array length is greater than 0 and the first and last elements are equal
return nums.Length > 0 && nums[0] == nums[nums.Length - 1];
}
}
}
```
```

Sample Output:

```False
True
False
```
