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.
I think, this solution can work faster.
If we storage pows for digits in HashMap.
Like this.
HashMap <Integer,Integer>;
So, we can calculate pow BEFORE seek and only once.
And in calculation we dont need spend time for pow calculate.
It's a JAVA8 style and so powerful :)
my solution is so shitty belong to this one ;D
The eqSumPowDig is easy to understand, but the hasProperty is in chinese.
Thanks!
