Your task is to decide whether the solution is correct or not. If the solution is correct, return the index of 1 and if not, return the index of 0.

Don't try to solve the problem. Your task is only to critique the solution.

Please put your final answer (i.e., the index, which must be 0 or 1) in \boxed{{}}. Every output must therefore contain either \boxed{{1}} or \boxed{{0}}.
