String comparison with foreach loop. The expected output is "Facebook"

Question

How can we compare two elements in a string and display the most repeated value using the foreach loop?

class Program
{
    static void Main(string[] args)
    {
        string[] values = { "Facebook", "Google", "Facebook" };
        foreach (var value in values)
        {
            // need to comparing the elements in the array 
            Console.WriteLine(value); /* print the repeated value*/
        }            
    }
}

You could do this pretty easily with LINQ

var mostRepeatedValue = values
                          .GroupBy(v => v)
                          .OrderByDescending(gp => gp.Count())
                          .Select(g => g.Key).FirstOrDefault();
