What was made with simple 1242!
During a long time i had Wa2 but with the same code
have AC now!
It should be said about mistakes in tests for 1242
and their correcting.

Sorry. We have fixed a bug in 2'nd test several days ago and haven't rejudged all wrong verdicts yet. Now they are rejudged. Your old submissions are AC.

Does it mean that you rejudged test like

' 'number' 'number
to
number' 'number?
