Obtain the index of the maximum element

Question

Given such a list:

        List intList = new List();
        intList.Add(5);
        intList.Add(10);
        intList.Add(15);
                


        

Answer 1

Here's the non-linq method if you like:

private int ReturnMaxIdx(List intList)
        {
            int MaxIDX = -1;
            int Max = -1;

            for (int i = 0; i < intList.Count; i++)
            {
                if (i == 0)
                {
                    Max = intList[0];
                    MaxIDX = 0;
                }
                else
                {
                    if (intList[i] > Max)
                    {
                        Max = intList[i];
                        MaxIDX = i;
                    }
                }
            }

            return MaxIDX;
        }

This is a single pass through the list at least.

Hope this helps,
