In SnackDown 2017 Online Elimination Round yesterday, I cannot get AC from problem Waiting in a Queue during contest.
After many hours of contest, I found a bug of my code:
The correct input format of this problem is:
n
a1 a2 ... an
b1 b2 ... bn
But I read Input as following:
n
a1 b1
a2 b2
.
.
.
an bn
I felt shocked after finding this bug. Why can I pass sample with this bug !!??
Then I saw the sample carefully. It shows:
2
3 2
2 2
I don't know how to use English to describe my though....
And I thought, if I get AC by just fixing this bug, I must post this bug on Codeforces!
Now it's the time.
