I was quite surprised that I received a book from a very, very dear Professor of mine. The book is an introduction to the study of Analysis of Algorithms and it is a pleasure to see a high-standard book (even if elementary) written in Portuguese.
Unfortunately, the translations of books like Cormen's "Introduction to Algorithms" are severely broken. They are not really worth the price and I would even dare to say that they do a disservice to the student that tries to learn from those books (Cormen's one in particular---be warned that I'm not talking here about the original English edition, which is superb, but the Brazilian Portuguese translation). There are many atrocities in the translation like translating "array" to "arranjo", while the usual, correct choices would be "vetor" or "matriz".
