0-1 Sequences Kattis Problem

Problem Statement

Code

I tried using the logic in this blog post, but I keep getting WA. My code uses the identity 0*nC0+1*nC1+2*nC2+...+n*nCn = n*2^(n-1).

Can someone please find the flaw in my counting method (or even better, provide a test case that breaks my code)?

Thanks in advance!
