So i gave this Div:2 #608. I was solving Problem C and I submitted the solution with pretest passed. I was not sure of this solution so I gave another solution by Changing boundary conditions. As it turns out ,the system testing checked only second solution giving me skipped verdict on my first solution thus -50 points. The solution which i submitted first was correct and gave me accepted when i submitted is later after the event. So does Code-forces check the latest solution only in system testing even if their is a potential correct answer before it?? This is just something i find weird. I know it doesn't matter a lot as this is just a contest and not very important but something like this should not be overlooked!!
