Consider a function $f\colon (0,1) \to \{0, 1\}$ defined as follows. For a real number $r \in (0,1)$ , $f(r) = 1$ if the second digit after the decimal point in $r$ is one of the four digits 2, 3, 6 and 7. Otherwise, $f(r)$ is equal to 0. The number of points in $(0,1)$ at which $f$ is discontinuous is __________. (answer in integer)
