Problem 1477. Champernowne Constant

  • Created by G K

The Champernowne constant is a real number whose digits in decimal representation come from the concatenation of all consecutive positive integers starting from 1.

That is

 0.1234567891011121314151617181920...

This constant is of interest because it can be understood to contain an encoding of any past, present or future information, because any given sequence of numbers can be shown to exist somewhere in the champernowne representation.

Return the nth digit of the champernowne constant. The function takes an array of position values and returns an array of digits corresponding to those positions.

Examples:

 [1 2 3 4 5] returns [1 2 3 4 5]
 [10 11 12 13 14 15] returns [1 0 1 1 1 2]
 [188 289] returns [9 9]
