🖥 Необходимо определить делегат и реализовать метод

Итак, вот задание:
определить делегат bool CounterHashSetDelegate(int a) и реализовать метод int Function12(HashSet<int> intSet, CounterHashSetDelegate filter), который возвращает количество элементов из intSet, которые удовлетворяют условию filter.
public static  class 
{
public delegate bool CounterHashSetDelegate(int a);
public static int Function12(HashSet<int> intSet, CounterHashSetDelegate filter)
{

int count = 0;
foreach (int i in intSet)
{
if(filter(i))
count++;
}
return count;
}
}



Давайте сразу к сути, решение может выглядеть так:
public delegate bool CounterHashSetDelegate(int a);

class Program
{
static void Main(string[] args)
{
CounterHashSetDelegate d = IsEvenNum;

Console.WriteLine($"Количество четных элементов:{Function12(new HashSet<int> { 1, 2, 3, 4, 5 }, d)}");

d = IsGreaterThen;

Console.WriteLine($"Количество элементов > 2:{Function12(new HashSet<int> { 1, 2, 3, 4, 5 }, d)}");

Console.ReadKey();
}

public static bool IsEvenNum(int a)
{
return a % 2 == 0;// четное ли число например
}

public static bool IsGreaterThen(int a)
{
return a > 2;//больше ли например
}


public static int Function12(HashSet<int> intSet, CounterHashSetDelegate filter)
{

int count = 0;
foreach (int i in intSet)
{
if (filter(i))
{
count++;
}
}
return count;
}

}

Вот и все дела

The lead from Wall Street offers little clarity as the major averages opened lower on Friday and then bounced back and forth across the unchanged line, finally finishing mixed and little changed.The Dow added 33.18 points or 0.10 percent to finish at 34,798.00, while the NASDAQ eased 4.54 points or 0.03 percent to close at 15,047.70 and the S&P 500 rose 6.50 points or 0.15 percent to end at 4,455.48. For the week, the Dow rose 0.6 percent, the NASDAQ added 0.1 percent and the S&P gained 0.5 percent.The lackluster performance on Wall Street came on uncertainty about the outlook for the markets following recent volatility.

What is Telegram?

Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
