Here: https://youtu.be/iRkMBjuqpWo?t=439, it's linked to the minute 7:19, since the compass starts arround the beggining of the second 20. Also see the bars, starting from the third one, up to the next 6, it modulates from Bb Maj to A# Maj.

Also, this piece uses quite a lot of "unusual" scales, but this is not strange to Chopin compositions.

The A# Major scale is more of a theoretical scale, usually the songs that could be in A# are written in its enharmonic equivalente Bb. This is done beacuse it´s more practical to only have 3 flats rather than have 4 sharps and 3 double-sharps.Yet some pieces, essentially in classical music, sometimes modulate to this scale during the song like Chopin's Polonaise-fantaisie in A-flat major, Op. 61, which modulates to A# major for six bars.

Ok, ok, I think it's done.

I'll fix it, just a note, by calling 40 different @test i call 40 different times the r, which then returns a different value so there are actually 40 different test, belive me i've checked.

Also, having the solution I use in the test class wouldnt be giving away a solution?
(Update) Nvm, I think I know what you mean now.

Ok, I think i´ve fixed everything

A LinkedHashMap is the closest to a object or a associative array in PHP
I hope is close and good enough for u :).

Excuse me im getting this error, for:
(123.45*(678.90 / (-2.5+ 11.5)-(((80 -(19)))
33.25)) / 20) - (123.45(678.90 / (-2.5+ 11.5)-
(((80 -(19))) *33.25)) / 20) + (13 - 2)/ -(-11).

expected:<1.0> but was:<1.0100000000002183>

¿Am I really doing something worng?,¿Should i round up somewhere?,¿Truncate?.

So, my Execution Time is bigger than 16000 ms, but on anytoher compiler it takes arround 14515 ms ¿Is the server to blame, my connection or should i just
try harder?
NVM, just cut my time to 186 ms, just found a way more efficient method
