If the term 'leak' refers to a tester or writer publicly disclosing the solution to the 'leaked' problem before the contest, then you must provide evidence to support this claim.

If, on the other hand, 'leak' means that someone randomly sent the answer to the problem into an unknown Telegram channel during the contest, I suggest you consider retaking your grammar exam.
