This article was originally written to know almost question "how to assess the 2019 ACM / ICPC Shenyang regional tournament site game?"
Blacksmith player, can be quite sad.
Let us talk about warm-up match:
A slow but steady hand up his teammates happy experience universal head.
B test the java for a long time, read all TLE, call the referee group, the referee group said they had over there java, it is curious how to write. Later, warm-up match to end seniors rub a java acceleration board.
C misread conditions, sample-oriented programming.
formal:
A big question read teammate heuristic fails, re-read. Later, with stl floating pointer, a little card.
On the number of D teammate nb.
H graph theory teammate nb.
K stormed blind guess, although at the time to know should not be stormed
L teammate analogy to Tetris, a step backward mathematical proof can swap AC, but in the end there is no AC. A method want intermediate segment tree maintenance
Horse-drawn carriage on the track M + dp, may also need to set a tree, but there is no board palindrome tree, dp write L teammates simulation method, the last time to dp. (On the Importance of three dp hand), although not dp positive solution, but it seems that the sample is weak?

Shenyang good comfortable qwq, good Northeast Heating happy qwq.
Reckon all the way, without a blacksmith off, no one thought escape Northeastern University does not offer only high orange juice latte.
Another year, come qwq.
(Say good ccpc final split it)
