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.

Sample Solution:

C# Sharp Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

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
