and the right answer is
4
3 4 6 5

2 4 6

in your case 2-th (#4 (2, 23)) and
4-th (#5 (2, 17) orders is expired

if you right, then why you can't

Please, explain! Why the answer to this test is:
4
3 4 6 5

Come on! It's easy to understand it.
For example this test
3
1 9
2 10
2 11
The answer is
2
2 3.
I can explain it. The deliver time is not exactly one day. So the second container (in my example) could be given in the first day and in the second day. So if the deliver time is N, it means that container could be given in 1, 2 ,..., N day (in any day, but not in the Nth day exactly). Hope it's clear to understand.

Thanks
