EXAMPLE

The 2nd digit of S is 3 and if n = 1 then a(1) = 2 and a(a(1)) = 3.

The 3rd digit of S is 1 and if n = 2 then a(2) = 3 and a(a(2)) = 1.

The 10th digit of S is 4 and if n = 3 then a(3) = 10 and a(a(3)) = 4.

The 6th digit of S is 1 and if n = 4 then a(4) = 6 and a(a(4)) = 1.

The 11th digit of S is 5 and if n = 5 then a(5) = 11 and a(a(5)) = 5.

The 9th digit of S is 9 and if n = 6 then a(6) = 94 and a(a(6)) = 9.
