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.
'looks like u solved it'
'sum |= 1<<e'
or
'sum ^= 1<<e'
will help, then check
'sum == 1022'
its slower but more reliable

provided str may not totally constructed by numbers (maybe: ' abc.sdf.sdf.sdf')

Hi bro! I think u forgot ont thing.
The sum equals 45 doesn't mean it is a sudoku!
I thought of this idea and then denied it.
Becasue 6+6+6 = 5+6+7.
I can put all 5 in a line but it's not correct!
I had never thought of function sort!Clever boy!
