PDF of a document I wrote in 1996 (in Portuguese) which is the solution
of  an  exam  of "Introduction to Programming" of my University made in
September of 1996  using  the  language  PASCAL. It  is  not  a  simple
solution since all steps are explained very  carefully  explaining  all
the logic behind  them and also the algorithms.  It  is  a must for all
people studying programming. Unfortunately I  lost  the  original  Word
document years ago when I formatted my  harddisk  and  I  only  had  it
printed in my old printer which didn’t have much quality too. So  I had
to scan what I had.
