'looks like u solved it'
'sum |= 1<<e' or 'sum ^= 1<<e' will help, then check 'sum == 1022'
its slower but more reliable
12. 12.12.12
I found it was because blank.For eaxmple :12.12 .12.12 is invalid IP.
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!
