Reverse a String in Every LanguagePublished on 01 November 2018 (Updated: 02 November 2018)
While Hello World is simple, it often does not show off many interesting features of a language. Fortunately, this repository shares more samples than Hello World. One of these more complex programs is known as Reverse a String.
In this repository, the algorithm must reverse ASCII strings. Do NOT worry about reversing a string in the general case. For instance, if a string contains surrogate pairs, it’s okay if the solution corrupts the string during reversal.
Despite the explicit name, there are some rules in place for consistency. When writing a Reverse a String program, the following rules should apply:
- The implementation must be executable
- The string to be reversed must come from the command line
- The program must verify the strings existence on the command line
- The user must not import libraries to obfuscate the string manipulation
In other words, the program should get a string from the command line and reverse it using language utilities only. Acceptable language utilities include language features and built-in libraries.
External dependencies are unacceptable. Remember, the goal is to show off language features and utilities.
If the solution passes these test cases, then it’s a good fit for the repo. Feel free to test other strings for fun. For instance, you may find that your language can handle unicode characters, but it fails for emojis.
