Question:
Find the function f: U=f(V) where V and U are vectors of size n. ∀ i:
V(i), U(i) ∈ N & 1 ≤ V(i), U(i) ≤ 28 & U(i) ≠ V(i)
U(i) ∈ EQAQ([J-3]:[J+3]) | EQAQ(j) = V(i)
where EQAQ is a circle of 28 symbols in the following order:
1, 10, 19, 28, 2, 11, 20, 3, 12, 21, 4, 13, 22, 5, 14, 23, 6, 1...
