Today, the amount of state title was okay but I did not write anything bad score today ... 80.T1 30 T2 10 points T3 40 minutes
But I can not deny that some of the issues subject of quality is still very good exposure:
1 and I misread the title and I and 2 and just a problem I have been obvious model for the rest of the write qwq 3 okay.
This question I tried various methods of cancer line of thinking is not valid 2h constantly trying new ways to build various types of edge Erase build anti map undirected shortest path tree ... I have been thinking a lot still can not find solutions to complex high problem. Or have the ring back to their own problems.
Positive Solutions I do not think its complexity is well-established (Well, I finally accepted its time complexity so complexity once for each point bfs nm
Served autistic qwq. What dynamic spfa what LCA consolidation method ... in fact, is nothing short circuit times. I do not think a simple way to know right.
Note that this problem read the question seeking a rectangle and the other rectangle of post and attention here and that is a rectangle and other rectangular cross misread the question then summed into a rectangle and a rectangular cross all
Do not instantly become a local post delivery needs to take very complicated I think a violent sweep pointer to the right and then take cross-section tree line marks the perpetuation of the tree line to achieve much impossible delegated lazy marker. So we can directly set the tree the tree.
The problem here is not that wrong to consider the correct reading questions correctly think I really admire himself out of thin air out of a very difficult topic to write my opinion and a certain number of rectangular cross take better approach I think is also the tree cover tree I did not write a good tree cover tree cover tree line segment tree I do not know how to write to the significant.
Moreover, no less than open space. Rectangular area of post and consider how similar requirements found or swipe scanning routine.
Good thought the cushions.
30 minutes 40 minutes explosive blast search Instant Instant Instant + prune descending i.e. to return to 40 points.
Alternative considerations like pressure F [i] [j] denotes the set of case i j is the remainder of the program number transferring apparent. Complexity of 2 ^ n * n * 10. 40 minutes can easily pass.
100 Obviously we are not like pressure, we also need to use modulo this determination, we also need to know the use of a set of very unhappy qwq
In fact, it seems to open dynamic array should be okay but high precision than max operating needs so it is still Xiecai. Complexity is still too high.
In this case there must be an alternative to the determination condition refers to a stronger determines whether a multiple of 11.
So with a lemma: is a number necessary and sufficient condition of a multiple of 11 bits is odd and even bit with the mold 11 and congruent. (I obviously do not push out.
This autistic I ... but can still prove its correctness provided a digital look variation feature a (a + b) (c + b) (d + c) (e + d) e is abcde * 11 consider then obviously do not carry.
So if there is a carry or even odd items items -10 -10 +1 or even items so odd item -1 is a multiple of 11 are summarized provable conclusion is correct.
Then we can be a linear dp. Still do not consider myself a think.
Here a temporary solution to a problem releasing the goo.
