Comments

a(8) = 2008...888 (156 digits).

Examples

			4 is represented with 4 segments, so a(1) = 4.
2 is represented by 5 segments, 5 is represented by 5 segments so a(2) = 2.
1 is represented by 2 segments, 2 is by 5, 5 by 5 again, so a(3) = 1.
[...]
1088 is the solution for 7 steps.
2008..888 (156 digits) is the solution for 8 steps.
