Don't it mean he only deliver one whisky on one day?
I don't know the test while the others programmer offer...
Who can tell me what the problem mean?

example :

3

1 10           (order: 1)
2 15           (order: 2)
2 17           (order: 3)

the answer:
2
2 3
```````
The result  don`t have (order: 1), because the last arrive day is 2, mean the man deliver twice, one day one once, the  subject mean it find out max profit in no more than the last day

4
1 17
5 20
2 10
2 11

answer:
3
1 4 2

Do you understand ?

Thanks！！！

Can I answer in the first test "3 2"?

Nope) "1 4 2" answer gives a 17+11+15=43$ reward. And there is no other sequence of delivery that will give us $43 reward.
