Consider the data type `Carte`, defined as follows: ``` struct Carte { char titlu[60]; char autor[60]; int an; }; ``` where `titlu` and `autor` are each a single word (no spaces), and `an` is the publication year. Read from standard input a natural number `n` and a year `y`, then the data for `n` books. Print on the first line the number of books published strictly before year `y`, and on the following lines those books, in the order they were read, one per line, in the format `titlu autor an`.
