"To make it fun for the spectators!"
INTERVIEW
What inspired you to start competitive programming?
My middle school teacher suggested me to do it.
How many on-site contests have you participated in?
Probably around 80–100?
What were your results in those contests?
Better than today.
What types of problems do you enjoy?
I enjoy problems where one needs to both come up with ideas on paper or in one's head, and first explore the problem space using the computer in order to do so.
Do you have a favorite problem on AtCoder?
Do you follow any pre-contest routines?
Not really, I try to sleep well the night before :)
Do you remember the first problem you solved?
Not the first one, but one of the first was about computing 2 to the power of 10000.
What music do you listen to while solving problems?
That would be too distracting, so I prefer silence.
What is the most challenging problem you've ever solved?
I can't remember one particular challenging problem.
What do you usually do on holidays?
Most often we travel somewhere with my family and do sightseeing.
Who is a competitive programmer you respect?
rng_58
How many hours of sleep do you get?
8
What are your aspirations for AWTF2026?

"Pronounce everyone's names correctly!"
INTERVIEW
What inspired you to start competitive programming?
During the first year of my university, I had a chance to talk with the best Polish competitive programmers at the time. I remember that I thought they are not that smart, so I might try it as well 😅
How many on-site contests have you participated in?
A few + 1
What were your results in those contests?
Good enough to be invited as a commentator!
What types of problems do you enjoy?
Ones that do not require implementing beam search.
Do you have a favorite problem on AtCoder?
Every problem that didn't require beam search is my favorite one.
Do you follow any pre-contest routines?
Try to get enough sleep, it never works.
Do you remember the first problem you solved?
lol, no
What music do you listen to while solving problems?
psytrance/dubstep/hardcore
What is the most challenging problem you've ever solved?
It's heuristics, we don't solve problems, we just give up at different times.
What do you usually do on holidays?
I'm retired, my entire life is a holiday.
Who is a competitive programmer you respect?
Everyone
How many hours of sleep do you get?
Something between 2 and 12
What are your aspirations for AWTF2026?
Pronounce everyone's names correctly!
