MO Team Algorithm Summary preface:Again, like the Chairman tree, Oi god Ben invented the algorithm.When I first heard the name of the algorithm, I guessed that the team was a great god Ben. Did not expect to know that he unexpectedly is our seniors! If you do not see the person, first smell his name!Until later CJ was designated as the PKUWC, CJ renovated the engine room and hung up the honor wall in order to provide a better environment. So I can see

Next there are m lines, each line containing four integers u, V, A and B, which means that the person wants to count the number of Apple U to Apple V, and this person thinks color A is color B. If a=b=0, it means that the person does not suffer from color blindness. OutputThe output is a total of M lines, each line contains only one integer, representing the number of colors the p

This complexity is only N*SQRT (n) ...Bare team tiles, first offline, then by the left end of the block, by the number of blocks as the first keyword sort, and then by the R value as the second keyword to sort. are small to large, can prove that such a complexity of only N*SQRT (n). Then the transfer between blocks is performed.The code is as follows:#inc

If you do not want to see a direct look at the next article, more important and effective.This problem is not already used online algorithm a over, how to again?Don't forget! The range additive was used before!This time the algorithm does not use the interval to be additive, also does not have the interval to reduce the sex, how does it do?From one endpoint to the interval of each point

Block of sequencesFor the query operation, the
number of a[i]^k, and update the answer on the LINE. The above is a different or processing part. Next is the MO team Algorithm. The MO team algorithm is a brute force algorithm used to solve interval problems. His principle is that if I know the value of [l,r], I can find the values of [l+/-1,r] and [l,r+/-1] at O1 time, then the values of query [l+/-k,r] and [
pairs of i and J for the first query is: (1, 2), ( 1, 4), (1, 5), ( 2,3 ), (3, 6), (5, 6), (6, 6). Not a single of these pairs are suitable for the second query. In the second, the sample XOR equals 1 for any subarrays of an odd length.Main topic:There is a series of N of length, M query (L,R) within how many pairs (i, j) make Ai ^ ai+1 ^ ... ^ aj = K;Problem Solving Ideas:The interval query here is offline and can be used in the legendary MO
First with the MO team algorithm to ensure the complexity of the transfer between inquiries, each transfer requires O (sqrt (m)) insertion and deletion, the weight of the block insertion/deletion is O (1).Then ask the time with the weight of the block query interval k small value, each time is O (sqrt (n)).So the total complexity is O (m* (sqrt (n) +sqrt (m)).The
