MCQ
If $f(x)=\left\{\begin{array}{c}\frac{\sin [x]}{[x]+1}, \text { for } x>0 \\ \frac{\cos \frac{\pi}{2}[x]}{[x]}, \text { for } x<0 ; \\ k, \text { for } x=0\end{array}\right.$
where $[x]$ denotes the greatest integer less than or equal to $x$, then in order that f be continuous at $x=0$, the value of k is
