seems simple, but is the most easily overlooked. Even a few minutes of negligence can cause harm to the system.　　　　Security of file encryption　　　　The crypt command can be provided to users to encrypt files. It uses a keyword to encode the standard input information into unreadable messy strings and sends them to the standard output device. Use this command again to apply the same keyword to the encrypted file to restore the file content.　　In general, the original file should be deleted after th

The basic idea of greedy algorithm: through a series of steps to construct the solution of the problem, each step is an extension of the constructed part solution, until the complete solution of the problem is obtained.Greedy algorithm, each step "greedy" to choose the best part of the solution, but do not take into account the impact of such a choice on the overall ( local optimal), so the global solution is not necessarily the best solution, but for many problems it can produce the overall opt

For Windows, it is an EXE and you can put it in a suitable directory, then add the directory to the system's PATH variable. 2. Then find a pysqlite, which is the python access SQLite interface, address here: http://initd.org/tracker/pysqlite Currently, for different Python versions, pysqlite has two versions: 2.3 and 2.4. Select one based on your Python version. 3. Then you
