Table of n, a(n) for n=1..5.

Tanya Khovanova and Gregory Marton, Archive Labeling Sequences, arXiv:2305.10357 [math.HO], 2023. See p. 4.

Example

a(5) = 40000000000 because the number of 5's in the decimal digits of the numbers from 0 to 40000000000 is 40000000000 and this is the 5th such number.
