1665C — Unable to understand the approach

Revision en1, by Flvx, 2023-09-14 16:21:38

This video(copied with time stamp) presents an approach to solving problem 1665C and I understood the broad approach but I am not able to understand that if we have the sum of left over vertices after considering infection is greater than the number of injection operations remaining we directly say that x is not possible, but shouldn't we also consider the fact that even if we have less injections left, they would all still spread in parallel at any given time?
