When I checked the submission of 301B, I found some accepted submissions failed in the following case:

input:
3 1000
5000
0 0
0 1
0 3

output:(which I think is correct)
1000

Am I correct? Is there anyway to update the test case and maybe rejudge acceptance?

Thanks

UPD Thanks Miras321. It turns out that I am wrong. I missed one constrain.
