The key output is wrong, what could be the problem?

  • Write in the question: input data and expected result. And why do you think that the result in the question code is wrong - gil9red
  • @ gil9red changed, look. I, by the key that displays, I can not check whether the progress of the computer was changed. - EgorKa
