WebJan 31, 2024 · Summary. We normally expect a binary search to have complexity of about O ( l o g N), and only descend to O ( N) in relatively rare worst cases. In this case, we get O ( N) in about the best case, and O ( N 2) in the bad cases. This violates the normal expectations of a binary search badly enough that it effectively only barely qualifies as a ...
