//CLEAN CODING WARNING: It's not good practice to have a method that does two completly different tasks
//This is just to make a point, good coding practices state that you would have a method
//that is responsable for performing any filtering operations and another one to print your data.
//If because of some restriction you have to, at least make sure the name of the method 
//states what is happening clearly.
public void FilterAndPrint()
{
	List<int> dataSource = new List<int>() {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
	List<int> valuesToRemove = null;
	IEnumerable<int> filteredData = new List<int>();

	try
	{
		filteredData = dataSource.Where(t => !valuesToRemove.All(x => x == t));
	}
	catch (ArgumentNullException e)
	{
		Console.WriteLine(e); 
	}

	foreach (var i in filteredData)
	{
