Discussion of Problem 1438. Time Limit Exceeded

Some hints
Posted by Fetisov Alex [USTU Frogs] 7 Apr 2008 12:41
I had WA4 because of this: AnD <=> and, NOt <=> not, etc.
I had WA9 because of this: empty strings (only spaces) - this is not a command))
I had TLE 13 because of this: we should ignore as a command lines has only a label)
Cool problem))
Good Luck)

Well, now you don't have AC :)

I can also add that you should do some pre calculations to get access to the variables' values and labels' positions with constant time. Logarithmic complexity isn't enough to pass TL.

Test 14 was added by me recently, which is why~
The only hint i can give for it is that the code prevented TL #13, but did it in not exactly a proper way.

Took some time to rewrite that crap and retake AC :)

Still don't know what was wrong in TL 14 of the previous solution though.
