Let $f(x)=\left\{\begin{array}{ccc}\frac{\sin (x-[x])}{x-[x]}, & x \in(-2,-1) \\ \{\max 2 x, 3[|x|]\}, & |x|<1 \\ 1, & \text { other wise }\end{array}\right.$
where $[t]$ denotes greatest integer $\leq t$. If $m$ is the number of points where $f$ is not continuous and $n$ is the number of points where $f$ is not differentiable, then the ordered pair ( $m, n$ ) is :
