some evidence

very AI-LIKE code, with SPACES between operators and variable names, and EMPTY LINES between parts and parts.

NO HUMAN-WRITTEN CODE in its DAILY practice, which means it performs without any practice(for human).

its performance in cfr1069 is TOO WELL comparing to other performances.

SKIPPED submissions in a round before cfr1069.

evidence of problem F

well, i have a question for its strategy: how did you switch to and think and then program F in 17 minutes?

and, during these contests, code speed is very need. YOU TYPE zero_adjust
