, filters or aggregations of Upstream data do not change the query semantics as much as possible. The optimization we are talking about is to filter and process data by the database as much as possible. This requires the following:
-Automatically identifies the parts that can be queried by the database
-Convert the corresponding part into the query language of the target database.
-Run the backend query and inject the result to the correct position of the data flow diagram.

Given a sequence of n numbers, find a continuous sub-sequence that satisfies such a condition:1. Average divided into three segments2. The first paragraph is the same as the third paragraph3. The second paragraph is the reverse of the first paragraph. The maximum length of such subsequence.Data range: n~100000

idea is simple, first determine the starting point:
The total number of points with odd degrees is 0, and any point is selected as the starting point;
The total number of points with odd degrees is 2, and a point in any of the two points is the starting point;
In other cases there is no solution.

Spring snow changes cause many roads in the world to be blocked by heavy snow, so that some students can not successfully reach the village where the Hui sound. So the comet decided to change to a village that could gather the largest number of people as a new teaching location. Th
First, the discussion1. Algorithm sourceThe basic principle of ant colony algorithm originates from the principle of the shortest path of ants foraging in nature, according to the observation of the insect, it is found that the ant of nature is not developed visually, but it can find the shortest path from food source to nest without any hint, and can change the environment (if there are obstacles on the original path). Adaptively search for the new best path.2, a single ant to find the pathPosi

the strong connected branch of G is C1, C2,..., Ck. The vertex set VSCC is {v1, v2,..., VK}, and for each strongly connected branch ci of G, a vertex VI is included. If there is a forward edge (x, y) for a x∈ci and a y∈cj,g, then there is an edge (vi, VJ) ∈ESCC. From another point of view, contraction of those whose associated vertices are in the same strong connected branch of G, you can get the figure GSCC.5, lemma: set C and c′ is a graph G = (V, E) in the two different strong connected bran
