Remove Items from list....Brain teaser

[Sl1ver]

Hi guys

I've got the following list

List<string> modelList = new List<string>() { "A", "B", "B", "A", "B", "A", "B" };
 

How will you make the list to only show the B's.

Rules.
No Linq
No new list variable or no use of array

So basically take the list as is, remove all A's

(Just interested in finding out how you guyz will do it)

I would use the RemoveAll method.

I'm not sure about the rules.

If you want to remove all "A"s and "B"s then just use modelList.Clear.

No LINQ? Why would you take that away?

private void RemoveA()
        {
            List<string> modelList = new List<string>() { "A", "B", "B", "A", "B", "A", "B" };
            for (int i = 0; i < modelList.Count; i++)
            {
                if (modelList[i] == "A")
                    modelList.RemoveAt(i);
            }
            for (int i = 0; i < modelList.Count; i++)
                Console.WriteLine(modelList[i]);
        }
