EXAMPLE
a(1) = 1 as a(0) = a(1) = 0 + 1 = 1 which contains '1' as a substring.
a(2) = 9 as a(1) + a(2) = 1 + 9 = 10 which contains '1' as a substring.
a(4) = 2 as a(3) + a(4) = 10 + 2 = 12 which contains '2' as a substring
a(49) = 1026 as a(48) + a(49) = 114 + 1026 = 1140 which contains '114' as a substring.
