Binary Search in Array - IP database problem
Back to Problem Solutions forum
There are a lot of rows in db-ip.txt where country code is empty, for example:
1ljj0tc 3
1ljj11c 73
If i found address from such range i represent it as empty string, but checker don't accept this.
I have refreshed page until it generated test case without empty countries and at least i have solved it.
Oh, my ugly English!
Wow, it is really bad - I should try to take care of this right now, since it is also used in the site's new functionality :-o
Thanks a lot for reporting this!
UPD: I've uploaded the filtered version of the file - there should be no empty countries. Really it is quite curious - original file contained about 100 such entries... I'm quite lucky you've found some of them :)
Looks like checker for this problem doesn't accept line with extra space in the end: it says "#### country codes expected". Number of codes in the line was correct but there was a space after the last one.
