Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
interesting
That's kinda the point of Code Golf lol.
The difficulty of the question is not in the question itself, but in the length of the code.
Please read the description and example carefully, and you'll know why.
If array1 has duplicate strings, result has too.
Great! The "odd-length" in the description suggests this solution.
Because the strtok will replace the delimiter as '\0', but input argument ip is const.
