Are you sure that tests for problem E are correct? I tried to assert whether the cities are indeed connected, and this gives RTE verdict (and without this assertion it gives WA).
We double checked the tests again, and the cities are already connected.
Looks like your RTE is caused by another reason. Maybe because the array
sthat you used should have the size ofNinstead of20Oops, my bad, sorry about that. Now I really wonder why my solution is incorrect:) Is there something special about testcase 43? Also, is it possible to submit after the contest?
It is fine :) You can upsolve the problems here.
all but one element of S is 0
It would be great if next contests have later starting time (at least 2-3h), this time is pretty bad for Europe.
Yes, we will try to have a later starting time for the next contests, as it is better for most of the current contestants as well
when editorial will publish.... and how to solve problem E in div2..
Editorial for English is being written. For problem Div 2E, the optimal answer is to "cut" the edge of the "median" of the diameter (if diameter is even, you have two edges to check).
