Half training can be okay ......
Half-simulation training for the first time
Examination process
It seems to be back on the same set of questions.

What the hell?
$chinese$？
In front of two background is?
Needs $ \ Theta (1) $ A pair resolved.

Remember modulo QwQ
Properties are:
1. Several of no more than $ f $ $ \ min (m, n) $ a $ [0, \ min (m, n)] $ (diagonal
More will be peers or column, so it can not be two maxima appear.
2. Therefore, according to the above idea: enumerate the number of f
Seems not to open $ 10 ^ 9 $, $ 10 ^ 8 $ can play with.
Then enumerate a maximum, as if still not out of $ \ text {ans} $
3. Continue want:
As if what the nature.
That does not affect the position of the maximum number of programs.
Combination count the position of the maximum value + + enum maintenance ranks intersection.
There can be three maxima intersect at one point (apparently
×× I will enumerate a maximum fried ah
$ \ Theta (k ^ {m + n}) $ this is ××
But what can pruning shears.
Better than violence and more but still want to dog T.
Maybe you can beat (and so will it) 60 stable
Than $ \ Theta (k ^ {mn}) $ stable point.
T2
physical……
×× is another matrix.
$\Theta(N^3)$??
Yes, and the prefix.
You can optimize it? ? ?

Violence minutes and very thick.
But after $ 10 ^ 9 $ is clearly unrealistic ~~

Be okay ......
And $ Co $ (cobalt) line ah ......
This is ×× ×× it. Not ah QAQ
But for tree rules, rules that tree? ?
Other ideas may not remember
As if really expect? ?

The idea is not it a bit longer ......
