using System;
using System.Collections.Generic;

class Program
{
    // Function to get a random value from a dictionary
    static string GetRandomValue(Dictionary<int, string> inputMap) {
        List<string> values = new List<string>(inputMap.Values);
        
        Random random = new Random();
        int index = random.Next(values.Count);
        
        return values[index];
    }

    static void Main()
    {
        // Initialize the dictionary
        Dictionary<int, string> myMap = new Dictionary<int, string>()
        {
            {1, "C++"},
            {2, "C"},
            {3, "Java"},
            {4, "C#"},
            {5, "Rust"},
            {6, "Python"}
        };

        string randomValue = GetRandomValue(myMap);

        Console.WriteLine("Random value: " + randomValue);
    }
}
