Impressed, the Elves issue you a challenge: determine the 30000000th number spoken. For example, given the same starting numbers as above:

• Given 0,3,6, the 30000000th number spoken is 175594.
• Given 1,3,2, the 30000000th number spoken is 2578.
• Given 2,1,3, the 30000000th number spoken is 3544142.
• Given 1,2,3, the 30000000th number spoken is 261214.
• Given 2,3,1, the 30000000th number spoken is 6895259.
• Given 3,2,1, the 30000000th number spoken is 18.
• Given 3,1,2, the 30000000th number spoken is 362.

Assignment

Given your starting numbers, what will be the 30000000th number spoken? Determine this in the following way:

• Write a static function recitation that takes two arguments: i) a list of starting numbers (String) and ii) a turn \(n \in \mathbb{N}_0\). The function must return the \(n\)-th number (int) spoken.

This static function must be located in the class Submission.

Example

> Submission.recitation("0,3,6", 2020)
436
> Submission.recitation("1,3,2", 2020)
1
> Submission.recitation("2,1,3", 2020)
10
> Submission.recitation("1,2,3", 2020)
27
> Submission.recitation("2,3,1", 2020)
78
> Submission.recitation("3,2,1", 2020)
438
> Submission.recitation("3,1,2", 2020)
1836

> Submission.recitation("0,3,6", 30000000)
175594
