Could I get help with sequential circuits

Q6. This is from Chapter 3, Problem 55 55. A sequential circuit has one flip-flop; two inputs X and Y; and one output, S. It conssts of a full-adder circuit connected to a JK flip-flop, as shown below. Fill in the characteristic table for this sequential circuit by completing the Next State and Output columns. Full Adder clock Present State Inputs Next State Output 0 0 0 0 0 1
