what should i do...

i think that a shift register is just a slow input line
it proceeds in each Clock pulse were in normal line they data comes straight away.


i was required to use it in the question

i dont have any idea of how to build this thing

when i tried to build the situation table
i came to the conclusion that building it in the normal way with flip flops
its impossible.its a 4 bit number
there are lots of possibilities
it would take me hours to write each one

i think they intended for some other solution

what should i do??
