During the contest my best solution for SEAVEC got 0.085 points and it was in the top 20 solutions for SEAVEC. Now after the rejudge the solution shows [0]points and my contest rank(global) has gone from 26 to 170. I don't understand how there can be so much difference when the test cases are randomly generated and I didn't use any random seed in my code. Is it possible that I got lucky on the first two test files and everyone else's code scored way more than me for the rest 8 files. This is very frustrating and if anyone has got an explanation for this, I'd be grateful.
