Let f(x) = \left\{ {\matrix{
{{{\sin (x - [x])} \over {x - [x]}}} & {,\,x \in ( - 2, - 1)} \cr
{\max \{ 2x,3[|x|]\} } & {,\,|x| < 1} \cr
1 & {,\,otherwise} \cr
} } \right.
where [t] denotes greatest integer t. If m is the number of points where is not continuous and n is the number of points where is not differentiable, then the ordered pair (m, n) is :
