Well thought-out URL-structure contributes to the proper functioning, successful scanning and indexing of your site by search engines...

In general, long-thought to make a theme with puzzles to programmers could pump your skills and do not rust.
There is a file with the following content ( link to the complete file):
Need to write the stream decoder that will parse a file filter objects, where scores> 0.7, and then burn these objects in the next file (also streamed). Download the entire file completely and unpack the array can not. Change the structure of the file from the task impossible. The output format is the same JSON. The final sorting is not important. Language is not important.
Not sure what the right decision. Just the top support)
Pro record in the results file is not immediately noticed.
But there is easy, if a blank simply write "[{json_encode found}]"
then go to the end, we find the position of the "]" and from that position we finish ", {json_encode found}]"
two lines then the extra - Only for counting time
an average of 0.03 seconds is performed on the core i5 quad

The problem is forbidden to ship the entire file

I asked you a quest, but do not want palitsya 🤪 But there purely algorithm, but can not fold it up to now, weak little minds: p

Yes, wrong in this case, my decision
Sly32, the output is not valid json :) Yes and subtract you all to memory.
My decision to Go, as usual - the longest https://play.golang.org/p/gWg-gqR-Xvi

Yes, I see, but have not yet found a beautiful solution. I do not like the idea of reading character by character file hands) with the validation like I know how to solve. While rummaging, that there is in python for such cases. The code that prinitspe of that php is approximately the same length will be

On php it can be even shorter if you do not read character by character.
That's decided to simple search:
If you do not ship directly into the memory of all, IMHO, only brute force and character work.
