Books published before year

Mobile coding works. A laptop is faster for long sessions.

Problem

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.

Input format

Input input.txt

The first line contains `n` and `y`, separated by a space. The next `n` lines each contain the title, author, and year, separated by spaces. - `1 <= n <= 500` - `1 <= y <= 3000` - book years are natural numbers between `1` and `3000` - the title and author have at most 50 characters and contain no spaces

Output format

Output output.txt

The first line of output contains the number of books published before `y`. The following lines contain the selected books, in reading order, one per line, in the format `titlu autor an`.
