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.
Can someone please explain to me why 10000000.00100000.00001010.00000001 is suddenly 2149583361? I cannot find sufficient information about this and I am lost.
All the time I'm getting this:
"./src/main/java/CountingDuplicates.java:3: error: cannot find symbol
List charList = new ArrayList<>();
^
symbol: class List
location: class CountingDuplicates
./src/main/java/CountingDuplicates.java:3: error: cannot find symbol
List charList = new ArrayList<>();
^
symbol: class ArrayList
location: class CountingDuplicates
2 errors"
WTF?!
