Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Just solved it.
The formula might be confused a little bit.
Honestly, i always take more time to solve g964 Kata because of deciphering the description.
Just realize i misunderstand the phrase
the first in order of appearanceExample case: BAABB
If you think B is first in order of appearance, it's wrong.
A is correct answer. It can paraphrase 'the first in order of appearance which have highest length`
Thank, it's helpful for me at least.
I am not good in math, i use wrong formula at first:
First: sin (x^3) - Second: (sin(x))^3
The first formula is wrong, when i change to second, it work like a charm and pass all test.
I have to agree with your comment. His explanation is just with one line but it exress better all description in the task.
Not all smart guy can be a teacher with same reason ^^.
Sorry, i still don't get it. Why rotating the dial clockwise (instruction step#2) from zero to 30 will take 90 degrees;
I am not sure what is the way to calculate the degree.
I just think the formula should be:
With clockwise start from 0:
0 -> 10 : 90 degree
0 -> 20: 180 degree
0 -> 30: 270 degree
With counter-clockwise start from 0:
0 -> 30: 90 degree
0 -> 20: 180 degree
0 -> 10: 270 degree
Can any one explain what's wrong with my formula?
------UPDATE------
After researching for a while, i realize my assumption is wrong.
The formula should be opposited base on the picture.

It help me visual the problem easily more than the image in task.
