[Lemon-devel] Quiz (good to know)

[Balazs Dezso]

Hi

I have an idea: 
1) Reallocate the storage area according to the current number of elements in 
the vector. /// \post v.size() == v.capacity()
2) Emptying the vector with deallocation of the storage area. /// \post 
v.capacity() == 0

I hope, that I'm the winner! :)

Best, Balazs
