a$)$ Using one Double Acting Cylinder, design a pneumatic circuit in which the cylinder cycles continuously for the duration push button is pressed. Upon releasing the push button the cylinder should stop cycling.

b$)$ Using two Double Acting Cylinder, design a pneumatic circuit in which both cylinders extend and retract in alternation to one another when a button is pressed. For example, as one extends, the other retracts, and vice versa. Please make the use of $\frac{3}{2}$ DCV push buttons, $\frac{5}{2}$ DCV$,$ End Position switches $($Limit Switches$),$ Shuttle Valves, Dual Valves and etc.

Give me answer by drawing this circuit in automation studio.
