And you cannot use sortedcontainers on codewars....

After having lost two days, looking on how to optimize my code on a kata where a very specific none intuitive purely mathematical optimization was needed (of course NO MENTION of this in the description), this kata was pure joy.
Basic logic and coding skill only were necessary.
I have trouble concentrating when playing video game( I get bored), when in the past I was able to play for hour on end, and when not playing I was thinking about the games.
Coding does that for me now :-) .
Thanks MMMAAANNN, I look at your kata yesterday evenning, I though about it at work, found the logical step to follow and implemented my solution this evenning. Remind me of playing Dagerfall as a teenager.
