# C# Sharp Exercises: Check if the first or the last element of the two arrays are equal

## C# Sharp Basic: Exercise-49 with Solution

Write a C# program to check if the first element or the last element of the two arrays ( length 1 or more) are equal.

Pictorial Presentation:

Sample Solution:

C# Sharp Code:

``````using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

public class Exercise49
{
public static void Main()
{
int[] nums1 = {1, 2, 2, 3, 3, 4, 5, 6, 5, 7, 7, 7, 8, 8, 1};
Console.WriteLine("\nArray1: [{0}]", string.Join(", ", nums1));
int[] nums2 = {1, 2, 2, 3, 3, 4, 5, 6, 5, 7, 7, 7, 8, 8, 5};
Console.WriteLine("\nArray2: [{0}]", string.Join(", ", nums2));

Console.WriteLine("\nCheck if the first element or the last element of the two arrays ( length 1 or more) are equal.");
Console.WriteLine((nums1[0].Equals(nums2[0])) || (nums1[nums1.Length - 1].Equals(nums2[nums2.Length - 1])));
}
}
``````

Sample Output:

```Array1: [1, 2, 2, 3, 3, 4, 5, 6, 5, 7, 7, 7, 8, 8, 1]

Array2: [1, 2, 2, 3, 3, 4, 5, 6, 5, 7, 7, 7, 8, 8, 5]

Check if the first element or the last element of the two arrays ( leng
th 1 or more) are equal.
True
```
