Read the source code, to learn to find the problem according to the source code, ask questions, let the problem in turn to drive reading sourceFor example, reading the Lucene search process willLook at the source, understand it to query to parse, there are cache related things, and there are other,Then we should ask questions according to these nouns.How to parse query, why to parse query;How to do the cach

Use BFS to solve the Maze problem and BFS to solve the Maze problemIn an n * n matrix, the path starts from the origin point (0, 0) to the end point (n-1, n-1). The path can only go in the upper, lower, and left directions, but only in the given matrix, calculate the minimum number of steps. N * n is the 01 matrix. 0 indicates that the grid has no obstacle. 1 indicates that there is an obstacle. Int mazeArr [maxn] [maxn]; // represents the 01 matrix i

In a set composed of n elements, order statistic is the smallest element in the set. For example, in a set composed of n elements, the minimum value is 1st sequence statistics, and the maximum value is the nth sequence statistics. The median always appears at low (n + 1)/2) or high (n + 1)/2, here, low is the downward round ("lower median"), and high is the upward round ("upper median"). When n is an odd number, there is only the "lower median ", when N is an even number, there are both "lower m

In the software system, because of the existence of a variety of character coding problems, such as another we have a very headache of Chinese problems. Therefore, it is now tending to use UTF-8 encoding as a coding format in software, thus avoiding the problem of most character encodings. This article is the same as the "80 ago" article, with Spring Project, please "Spring fans" of self-respect, nothing to disturb, the text of the deficiencies are we

To implement a database connection pool, singleton mode is essential, because the connection pool itself needs to be used in a large number of places, and the connection pool connection should be shared, so at least the connection pool to save the list of connected pools need to be static mode, so that the connection pool of the main class is implemented as a singleton mode, So the subsequent development code can be easily read some. When implementing the single-instance connection pool main cla

An engineer is naturally fond of solving problems, especially the bugs in his system. As long as a problem occurs, he wants to solve it. It seems that the more problems he can solve, the more value he can create. Such logic may be right in the development and maintenance of software for enterprises, but it is almost the most important reason to kill entrepreneurs in the consumer market. 　　Value of the problem
