Actually what we understood about the shift register concept i.e.
In the Right Shift register take the input of SI (First bit -> LSB bit) to the MSB flip-flop to LSB flip-flop.
In the Left Shift register take the input of SI (First bit -> MSB bit) to the LSB flip-flop to MSB flip-flop.
Because I have done Many questions in this concept, Even Gate also asked such kind of questions where Order of flip-flop matter. Please help me find the right concept for such kind of questions because here is ambiguity.
