Champernowne's constant

Problem 40
|
||
An irrational decimal fraction is created by concatenating the positive integers:
|
||
|
||
0.123456789101112131415161718192021...
|
||
|
||
It can be seen that the 12th digit of the fractional part is 1.
|
||
|
||
If dn represents the nth digit of the fractional part, find the value of the following expression.
|
||
|
||
d1 × d10 × d100 × d1000 × d10000 × d100000 × d1000000
