What was fast IO?

It toggles on or off the synchronization of all the C++ standard streams with their corresponding standard C streams if it is called before the program performs its first input or output operation.

Is Fast IO legit?

Fast.io is a simple CDN hosting platform for managing your files in your cloud storage. It is simple and reliable as everything is quick to access.

Which input method is fast in Java?

Using Reader Class It is the fastest method in java for input.

What is CIN tie null?

cin.tie(NULL); This unties cin from cout . Tied streams ensure that one stream is flushed automatically before each I/O operation on the other stream.

What is Veryfast?

very fast – in a relatively short time; “she finished the assignment in no time” in no time.

Which is faster Scanner or BufferedReader?

Scanner has little buffer of 1 KB char buffer. BufferReader has large buffer of 8KB byte Buffer as compared to Scanner. Scanner is bit slower as it need to parse data as well. BufferReader is faster than Scanner as it only reads a character stream.

What is faster than Scanner in Java?

BufferedReader is faster than scanner but it requires a lot of typing. BufferedReader class reads input from the character-input stream, buffering characters to provide an efficient reading of char, arrays, and lines.

Is Scanf faster than CIN?

With synchronization turned off, the above results indicate that cin is 8-10% faster than scanf(). This is probably because scanf() interprets the format arguments at runtime and makes use of variable number of arguments, whereas cin does this at compile time.

What is Ios_base :: Sync_with_stdio?

ios_base::sync_with_stdio In practice, this means that the synchronized C++ streams are unbuffered, and each I/O operation on a C++ stream is immediately applied to the corresponding C stream’s buffer. This makes it possible to freely mix C++ and C I/O.

Why InputStreamReader is used in Java?

The InputStreamReader class of the java.io package can be used to convert data in bytes into data in characters. It extends the abstract class Reader . The InputStreamReader class works with other input streams. It is also known as a bridge between byte streams and character streams.

Is Scanner in Java slow?

Using Scanner to parse input is convenient, but too slow. Using BufferedReader and StringTokenizer is much faster, but its a lot of typing during a competition.
