It just doesn't do what it's supposed to now.
namespace Treehouse.CodeChallenges
{
public class SequenceDetector
{
public virtual bool Scan(int[] sequence)
{
return true;
}
}
}
namespace Treehouse.CodeChallenges
{
public class RepeatDetector : SequenceDetector
{
public override bool Scan(int[] sequence)
{
for(int i=0;i<sequence.Length;i++)
{
if (i > 0)
{
if (sequence[i] == (sequence[i]- 1))
{
return true;
}
}
}
return false;
}
}
}

231,084 PointsIt looks like you may have placed a bracket in the wrong place. The comparison sequence[i] == (sequence[i]- 1)
doesn't compare two different array elements, it compares each element's value with the result of subtracting one from itself (which can never be true).
You probably intended to write sequence[i] == sequence[i - 1]
instead.
