Which of these is larger?
the total number of digits in the sequence 1, 2, 3, ..., 101180
the number of zero digits in the sequence 1, 2, 3, ... , 101181
Note: Champernowne's number is the real number 0.12345678910111213.... David Champernowne, while an undergraduate at Cambridge in 1933, proved that this is a "normal number": The digit distribution is, asymptotically, uniform.
