$\sqrt { \left \lfloor x+\left \lfloor \frac { x }{ 2 } \right \rfloor \right \rfloor } +\left \lfloor \sqrt { \{ x\} } +\left \lfloor \frac { x }{ 3 } \right \rfloor \right \rfloor =3$

Let the solution set of equation above be $$[a,b)$$ . Find the product, $$a b$$.

Clarification: $$\{ x\} = x- \lfloor x \rfloor$$.
