C# Sharp Exercises: Check specific digit in an array of numbers

C# Sharp Array: Exercise-38 with Solution

Write a C# Sharp program that takes an array of numbers and a digit. Now check whether the digit is present in the said array of numbers.

Sample Data:
({7, 5, 85, 9, 11, 23, 18}, "1") - > "Present"
({7, 5, 85, 9, 11, 23, 18}, "1") - > "Present"
({7, 5, 85, 9, 11, 23, 18}, "1") - > "Not present..!"

Sample Solution:

C# Sharp Code:

using System;
using System.Linq;
namespace exercises
{
   class Program
   {
       static void Main(string[] args)
       {
           int[] nums = { 7, 5, 85, 9, 11, 23, 18 };
           string n = "1";
           Console.WriteLine("Original array elements:");
           Console.WriteLine($"{string.Join(", ", nums)}");
           Console.WriteLine("\nDigit to search: " + n);
           Console.WriteLine("Check the said digit present in the array!: " +test(nums, n));
           n = "9";
           Console.WriteLine("\nDigit to search: " + n);
           Console.WriteLine("Check the said digit present in the array!: " + test(nums, n));
           n = "4";
           Console.WriteLine("\nDigit to search: " + n);
           Console.WriteLine("Check the said digit present in the array!: " + test(nums, n));
       }
       public static string test(int[] nums, string n)
       {
           return nums.Select(s => $"{s}").Any(a => a.Contains(n)) ? "Present" : "Not present..!";
        }
   }
}

Sample Output:

Original array elements:
7, 5, 85, 9, 11, 23, 18

Digit to search: 1
Check the said digit present in the array!: Present

Digit to search: 9
Check the said digit present in the array!: Present

Digit to search: 4
Check the said digit present in the array!: Not present..!
