As it was pointed in the comments we have a tricky point about hacks with problems D1/D2. 1. To avoid the situation when participant locked the problem D1 and looks the solution of the problem D2 in his room, you will be allowed to lock the problems D1/D2 only together in the same time and only if both of your solutions for this problems passed the pretests. In the other words, the possibility to lock D1/D2 will appears only after you solved both problems. The problems D1/D2 will be locked together in the same moment. 2. To avoid the situation of double reward for hack of D1 and D2 of the same participant, the participant X after successful hack of the participant Y on the problem D1 loses the possibility of the hack Y on the problem D2. Similarly if the participant X successfully hacks the participant Y on the problem D2, then X loses the possibility of the hack Y on D1.
