Lossy compressors don't have the same constraints as a lossless compressor. If you data your input, compress it, and then decompress it, the output is not identical to the input. This allows the compressor to potentially compress the data far more than even the ideal lossless compressor hypothesized above.
The question mark (?), also known as the interrogation point, query, and eroteme, is a punctuation mark that indicates an interrogative clause, or phrase in many languages. The question mark is not used for indirect questions.
It means: Are you? There is actually supposed to be question mark after that phrase, you can only use it in a question form. - Es-tu un membre d'equipe? (Are you a member of â¦ the team?). It is usually tu es, but when you are asking a question, you reverse the order and put a hyphen in between.
