- \$\begingroup\$ @Neil Although I can't imagine a situation where them being identical would cause problems, you can assume that all strings will be unique. \$\endgroup\$ATaco– ATaco2017-12-28 10:07:14 +00:00Commented Dec 28, 2017 at 10:07
- \$\begingroup\$ @ATaco It can certainly matter if you're not using built-in string comparison. \$\endgroup\$Dennis– Dennis2017-12-28 19:00:30 +00:00Commented Dec 28, 2017 at 19:00

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. code-golf), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
