Subject: [PATCH] A clearer description of the original problem
The original excercise instructs the learner to use the vector macro.
It is easy to assume that the code needs to read from `a` which is not
what is intended.
The updated excercise introduces the syntax for initial array and vector
contents and lets the learner figure out how to tweak initial values of
a vector. This learning seems to be the original intent of the
excercise.
