What do you mean by cheating?
It is always nice to have an easily readable file.
I might be wrong.
Quoted more than 1000 times (I hope).Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.
I think what the OP means is that the original file format is fixed, and can't (easily) be changed.

matsp is right.
Ok, im a tireless optimizer, i have improved t3 performance mark with the following parsing:
I was able to squeeze out 1,266 seconds from this function, over the 1.5s of before...Code:for (string::size_type i = 0;;) { while (line[++i] == '-' && i < end); //find first '-' character if (i >= end) { break; } begin = i; while (line[++i] != '-' && i < end); //find first not of '-' character dictionary[line.substr(begin, i - begin)]++; }
