        @smilingtadpole-1 In this problem, we do not care whether 11 has one or two 1s. What matters is the fact that 11 contains a 1. When you solved this problem, you assumed that because 11 had two ones, it should be counted twice, which is incorrect. I hope this helps!(also charge your device lol)

        Don't worry, I will die on the AMC10A. It's OK not to be OK!
