Ti and Di are integers (at least scanf doesn't balk).

I keep getting WA though. Am I right in surmising that when D rode all bicycles and there is still at least one minute before any snow white starts to cry, then, and only then, D has made it?

Furthermore, what's with ambiguous input? For example

3
1 9
2 8
3 7

should have six valid outputs:
1 2 3
1 3 2
2 1 3
2 3 1
3 1 2
3 2 1

Is one preferred over the others, or is the judge smart enough to accept any of them?

I don't understand the problem statement. Maybe a further example is needed.

Re: I think the prob stat is quite clear :-)
but I can explain the eg.:
If the order is 1->2: the dwarf (D) needs 2 min(s) to take the first Snow White (SW), then she can go alone for 11 min(s); while D must spend 11 min(s) more taking the 2nd SW before jumping on the bus, but after 11 min(s) the 1st SW will cry >> BAD solution

If the order is 2->1: GOOD solution, D has 11 min(s) to go on the bus before the 1st SW crys.

ok ;) sorry for my bad Eng
