Check for Both 5's and 7's in Array

Write a C# Sharp program to check whether a given array of integers contains 5's or 7's.

Visual Presentation:

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 result of the 'test' method with different integer arrays as arguments
            Console.WriteLine(test(new[] { 1, 5, 6, 9, 10, 17 })); // Testing the method with an array
            Console.WriteLine(test(new[] { 1, 4, 7, 9, 10, 17 })); // Testing the method with another array
            Console.WriteLine(test(new[] { 1, 1, 2, 9, 10, 17 })); // Testing the method with a third array
        }           

        // Method to check if the array contains either the number 5 or the number 7
        static bool test(int[] nums)
        {
            // Looping through the array
            for (int i = 0; i < nums.Length; i++)
            {
                // Checking if the current element is either 5 or 7
                if (nums[i] == 5 || nums[i] == 7)
                {
                    return true; // If 5 or 7 is found, returning true
                }
            }

            return false; // If neither 5 nor 7 is found, returning false
        }
    } 
}

Sample Output:

True
True
False
