Title Link: BZOJ-2821Problem analysisBecause the force is online, so can't use Mo team. You can use chunking to do this.This is done by dividing the number of n into n/x blocks, each with a block size of X. Pre-F[I][J], which indicates the number of occurrences of the numbers from block I to block J is even.This complexity is n * (n/x).Then put the number and position in the structure, according to the number of the first keyword, the position of the second keyword sort. This is to facilitate th

Question meaning:
To a matrix of N * n, some locations are empty, and some locations have boxes (A represents a box, B represents two, and so on ). Let you select an empty position as the starting point, and then select a direction (top, bottom, left, right) for each step until it hits the box, and then remove the box at this position, all the remaining boxes are merged to the next po
The main topic: give a sequence, to find the number of occurrences in a period of a positive even numbers.Train of thought: 50000, sub-block. The main thing is to deal with two arrays, one is the answer to the whole block, the space complexity is O (√n*√n), there is a prefix and the number of times each block appears, the Space Complexity O (n*√n). Then it was violence. The code is messy, and you need to analyze the complexity of the time based on for.This question probably does not need to read

The goal is to clear the blocks by pushing into them.You shoshould choose an empty area as the initial position of the PusherBoy. then you can choose which direction (U for up, D for down, L for left and R for right) to push. once the direction is chosen, the PusherBoy will walk ahead

Therefore, the author believes that network administrators should consider the applications deployed on the enterprise's current or future network when considering which product of the specific series to use. If an enterprise now has a vro that supports voice data independently, it will be a waste to use vrouters 2821 durin

The Rfc-igno-rant.org goes further by blacklisting email servers that violate RFC 821 and 2821 (RFC 821 and 2821 are the main specification for SMTP communication ). Unfortunately, a considerable number of legitimate email servers violate these rules due to poor design or incorrect implementation. Users who use these email servers may be blacklisted by the rf

However, depending on the different equipment, HDMI is sometimes not the best choice, if your family's equipment has a certain age, and just need to sound bar such a simple sound output device to connect to the TV, then the fiber audio is a good way to connect. In this case, sometimes the only option is not to worry too much about HDMI. For most simple sound devices, fiber and HDMI are actua

any positive integer A is less than n to modulo n, the result is still a.Its inverse proposition is that a is any positive integer less than n, if a ^ n% n = = A, then n is a prime number. Unfortunately, this inverse proposition does not hold, because there is a class number called Carmichael number, it conforms to a ^ n% n = = A This feature, but is not a prime. Using this program directly to check if a number is a prime has a big chance of making a mistake. This is part of the known Carmichae
