Every previous number can be at most half the next number. (2, 3, 10) is ineligible, because 2 > 3/2

Because it's a "polyfill" of ES6's built-in BigInt class

Try doing it by hand first. Then let the computer do what you did.

it happens because

some transcription factors could have overlapping binding sites with others (or with themselves).

So the ATF6: "TGACGT" binds the sequence "TGACGTGACGT" twice at index 1 and 6 with an overlapping T:

TGACG|T|
     |T|GACGT
TGACG|T|GACGT
1     6

the "TGCGTGCGTG" sequence relative to AhR: "TGCGTG" contains an overlapping TG:

TGCG|TG|
    |TG|CGTG
TGCG|TG|CGTG
1    5

Hope it is clear now, cheers!

No problem;)

@Steven Pavlovskii, what the kata lang?

Input is coordinates of all points. You just have to calculate two points which have max distance between them. you have to output the max distance you get.

It is the bitwise XOR operation.

a ^ b is the same as Math.pow(a, b). Just exponents / powers of numbers.
