Identical regexp can or cannot run in linear time depending on your ruby binary. Neither forward nor backward compatibility is guaranteed about the return value of this method.
Ruby is a simple and powerful object-oriented programming language, created by Yukihiro Matsumoto (who goes by the handle “Matz” in this document and on the mailing lists).
Operators In Ruby, operators such as +, are defined as methods on the class. Literals define their methods within the lower level, C language. String class, for example. Ruby objects can define or overload their own implementation for most operators. Here is an example:
Ruby was first developed by Matz (Yukihiro Matsumoto) in 1993, and is now developed as Open Source. It runs on multiple platforms and is used all over the world especially for web development.
Ruby user groups are entirely devoted to Ruby. They typically feature monthly meetings, a mailing list, a website, and if you’re lucky, frequent hacking sessions (meetings devoted to giving people a chance to write Ruby code).
As with most programming languages, Ruby leverages a wide set of third-party libraries. Nearly all of these libraries are released in the form of a gem, a packaged library or application that can be installed with a tool called RubyGems.
Ruby’s grammar differentiates between statements and expressions. All expressions are statements (an expression is a type of statement), but not all statements are expressions.
Please see the GitHub releases for further details. This version is a final release of Ruby 3.1 series. We will not provide any further updates including security fixes for Ruby 3.1 series. We recommend you to upgrade to Ruby 3.3 or 3.4 series. Download https://cache.ruby-lang.org/pub/ruby/3.1/ruby-3.1.7.tar.gz
