An inquisitive student should solve such problems independently
- otherwise, how else he (or she) will develop his (or her) mind ?

// of course, if he (or she) in reality has such a goal - to develop his (or her) mind,
which is not obvious for advance.

At least, he (or she) must make first step/steps on his (or her) own.
