check if the sequence of digits after the decimal is non-terminating and non-periodic.

This is a problem frm I.A.Maron's book
0.1010010001......1000...(n times)1.... is irrational
To prove this, it is necessary to ascertain that the gicven decimal fraction is not a periodic one. there are n zeroes between nth and (n+1)th unities, whcih cannot occur in a periodic function.
