Split nums into two arrays A and B using the following rule:

    -
  • Elements at prime indices in nums must go into array A.
    • +
  • Elements at prime indices in nums must go into array A.
  • All other elements must go into array B.

Return the absolute difference between the sums of the two arrays: |sum(A) - sum(B)|.

-

A prime number is a natural number greater than 1 with only two factors, 1 and itself.

-

Note: An empty array has a sum of 0.
