🖥 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

If riding a bucking bronco is your idea of fun, you’re going to love what the stock market has in store. Consider this past week’s ride a preview.The week’s action didn’t look like much, if you didn’t know better. The Dow Jones Industrial Average rose 213.12 points or 0.6%, while the S&P 500 advanced 0.5%, and the Nasdaq Composite ended little changed.

Tata Power whose core business is to generate, transmit and distribute electricity has made no money to investors in the last one decade. That is a big blunder considering it is one of the largest power generation companies in the country. One of the reasons is the company's huge debt levels which stood at ₹43,559 crore at the end of March 2021 compared to the company’s market capitalisation of ₹44,447 crore.
