Using the definitions

write a procedure

that computes the number of rows *rows* and the number of columns *cols*
of the smallest subrectangle with horizontal and vertical sides
that contains all the occurrences of *c* in *r*.

**Precondition**

The character *c* occurs at least once in *r*,
which is really a rectangle.
That is, all rows have the same number of characters.

**Observation**
You only need to submit the required procedure;
your main program will be ignored.
