Coding is to solve a certain problem (whether it is a question on OJ or a project). Before solving the problem, we should fully analyze the problem (mining the implied conditions of the question, analysis of project requirements), coding becomes a matter of course only after you fully understand the problem and have a clear idea. In the past, when I was doing a question on OJ, I used to write code when I saw the question and never analyzed the various

did you knowalgorithm is very interesting. At first glance, it seems that someone is planning to write the word "logarithm" (logarithm), but the four letters are reversed. This word was not found in Webster's New World Dictionary (the New World Dictionary of Wei's) until 1957, we can only find the old form of "algorism" (arithmetic) with its ancient meaning, which refers to the process of arithmetic operations using Arabic numerals. In the Middle Age

} NtoS. keys () # = "dict_keys (['two', 1, 2, 'one']) # Delete the member del NtoS ['one'] NtoS # = "{'two': 2, 1: 'one', 2: 'two'} whose key value is one '} Dictionary efficiency is very high, because the hash algorithm enables us to retrieve members in linear time. That is to say, even if the number of dictionary elements increases, efficiency will not be affected.3. pseudocode Pseudocode is used to des

Pseudocode and Flowchart I. Syntax Rules of pseudocode(1) In pseudocode, each command occupies one line; (2) The command is not followed by any symbol (the statement in C should end with a semicolon );(3) The "indent" in the writing indicates the branch program structure in the program. The statements of the level-1 module are indented to those of its parent modu

note when writing high-quality pseudo codes: Avoid using the syntax in the target language for description When writing pseudo code, there is also an iterative process. First, we start to design the code at the High Level, constantly breaking down the problem, and discovering details until we can quickly write the pseudo code. Finally, it should be noted that a well-written pseudo code can serve as a comment !!! The general process for defining

Implement read/write locks and read/write locksExclusive lock disadvantagesData is shared among multiple threads. The common practice is to lock read/write, that is, only one thread can read or write data at the same time point to ensure data consistency, that is, thread security. For example, the following
