I organized a two-day contest and I need to merge the rankings. Any idea how I do this? The answer is kind of urgent. Thx

Hello, CF community
Yesterday, I was challenged by my dear friend and competitor activedeltorre to solve the problem textmare(https://kilonova.ro/problems/199) which he bragged about already solving it. As the rating suggests, I am far more skilled and I couldn't accept such disrespect, so I accepted the challange. After 64 submissions(compared to his 75) I, of course, solved the problem and proved my worth once again.
