Use the Python and vim plug-ins to allow Vim to support multi-Folder comparison, On Vim's official website, there is a plug-in DirDiff that supports 2 folder comparisons. Link: http://www.vim.org/scripts/script.php? Script_id = 102. However, only two folders are supported. I aligned the research and improved IT TO MAKE IT support comparison of files in Multiple folders. The basic principle of the DirDiff pl

Comparison operatorsComparison operators can use a comparison of two values, and all built-in types support comparison operations. When you compare two values with an operator, the result is a logical value, not true, or false.One thing to note is that different types are compared differently, numeric types are compared by number size and positive and negative, a

The comparison operators in PHP are a bit weird and prone to errors, and now the comparison rules are listed:1, when the size comparison of two characters, is compared to the ASCII size of the two characters-this article is easy to understand.2, when the size comparison of two strings, is starting from the first charac

Comparing strings is one of the most important features of string processing in any programming language. In addition to using comparison notation (= =, 1.
