Can't figure out how to set up the method in this code challenge

Override the Scan method to return true if any value in the array is a repeat of the value immediately preceding it.

namespace Treehouse.CodeChallenges
{
    class RepeatDetector : SequenceDetector 
    {
        public override bool Scan(int[] sequence)
            if()
            {

            }
    }
}

Are you having issues with the overriding itself? Or just writing the logic in the method?

In a case like this, I'd iterate through each value in 'sequence' starting at index 1 (not 0), and check if sequence[i - 1] == sequence[i]

eg. for (int i = 1; i < sequence.Length; i++) { if (sequence[i - 1] == sequence[i] return true; }

return false;
