It assigns variable length code to all the characters. The code length of a character depends on how frequently it occurs in the given text. The character which occurs most frequently gets the smallest code.
WebAbout. WTF is CTF? There are a lot of Capture The Flag (CTF) competitions in our days, some of them have excelent tasks, but in most cases they're forgotten just after the CTF finished.
