Why? Put your reason in the following box. You cannot simply say the number of a's is not the same as the number of b's. The TM cannot tell if the number of a's is not the same as the number of b's. It would reject a string only if it reaches a point that it cannot proceed any further and the state is not the ‘halt' state.
