I got a physics problem with harmonic motion that i dont know how to do?

An object (object #1) of m M is attached to a spring with spring constant k. The other end of the spring is attached to a rigid wall. A second object (object #2) of m M is attached to two springs (one on each side of the object), each with a spring constant of k/2 (the other ends of the springs are attached to rigid walls). Each object is displaced and let go, causing harmonic motion. How does the frequency of oscillation of object #1 compare to that of object #2?
