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.
Make sure that there is a whitespace. It's "' '{3}" not "{3}". :)
doesnt work for me :/
3 spaces you could use " {3}" instead~
This comment is hidden because it contains spoiler information about the solution
it checks whether there are more than one whitespace and splits
StringBuffer is way slower than StringBuilder, because it is synchronized. And if nowadays you see StringBuffer anywhere in single threaded code it is archaic (or poorly written) code.
BTW code from kata with +="" whould compile to StringBuilder concentrations, very inefficient ones however.
first ,U should add this code:
morseCode.isEmpty() return "";
second ,
StringBuffer result
result.append()
how this works? word.split("\s+")?
