Modify it to implement an SR latch. The starter circuit should already have two inputs - S and R, in that order - and two outputs - Q and Q', in that order.

Your circuit should behave as follows:

If S is set to 1 and R is set to 0, this should cause Q to become 1 and Q' to become 0. If you then change S to 0, Q should stay at 1 and Q' should stay at 0.

If S is set to 0 and R is set to 1, this should cause Q to become 0 and Q' to become 1. If you then change R to 0, Q should stay at 0 and Q' should stay at 1
