Test instructions: Given a tree, each node has color, and for each query (U,K) Ask how many color occurrences are under the subtree of the root node in U >=kBecause it is a subtree, which is related to the DFS sequence, it is transformed into an interval, which can be solved by the MO team algorithm.The color of the number of occurrences >=k directly with an arrayCode#include [CODEFORCES375D] Tree and Queries (Mo

Today we review the contents of the tree-like array.It can be said today only to understand the meaning of the tree-like array. No impression of the previous understanding.Now, Mark here.Tree-like array:A tree-like array is a special data structure used to store data. Specific shapes such as:A array is a general form of our macro, and C is a relatively tree-like array.In binary condition:A[0] to a[1110] and =c[1110]+c[0110]+c[0010];Modified a[1], affected by c[1],c[10],c[100],c[1000] .....For su

For this kind of interval query problem, if can use the complexity of O (1) to a Manhattan distance of 1 of the other interval, you can directly use the MO team algorithm.There are two kinds of pointers from the Internet. The first is to establish the minimum spanning tree in Manhattan and then direct DFS to traverse the entire tree to solve it.There is also a block first, and then the query according to the block number of the first keyword, the righ

EXGCD, any set of conditions to satisfy the solution can be. 2. By Fermat theorem x^ (m-1) ≡1 (mod m), xxx^ (m-2) ≡1 (mod m) so x^ (M-2) mop m is the multiplication inverse of X. The rest of the interval query using the MO team algorithm to divide an interval into sqrt (n) blocks, and then press sqrt (L), R sort. The time is approximately sqrt (n) * (n).#include #include#include#include#include#include#includeusing namespaceStd;typedefLong LongLL;Con
Bzoj_3289_mato File Management _ Mo Team + tree-like arrayDescriptionmato students from all the way God Ben in a variety of ways (you know) collected a lot of information, there are a total of n copies, each has a size and a number. To prevent others from stealing, the data is encrypted and can only be accessed using a program written by Mato. Mato randomly selected an interval every day [L,r], and today he looks at the data numbered in this interval.
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 constants are very small.Other data structures that are maintained by weight cannot be in

The MO team algorithm thinks that after the left endpoint is sorted, the left end of the terminal movement must be few, but the right endpoint moves much more often. If you reduce the number of right end moves appropriately, even a little bit more left end-point moves can be cost-effective in total co
