Relevant equations
N/A


The attempt at a solution
Based on the diagram in the link I provided, I know that:

JA = QB'
KA = 1
JB = QC'
KB = QC
JC = QA
KC = QA

The problem is I do not know what to do after that. Can anyone explain to me how to do this? Thanks.

Do you know how a JK flip-flop works?

What happens if A,B,C are active and we get the next clock cycle?
What happens if A,B,C' are active?
What happens for all other combinations?
