You are doing the study of amoeba. There are two types of beakers:
On the first day, they put 1 amoeba in Beaker2 and after every 24 hours the total count of amoeba doubles.
If on any particular day Beaker2 overflows, then you transfer only amoeba to Beaker1 and discard the rest of amoeba.
From the next day, you start with 1 amoeba again and repeat the process infinitely. Determine the number of days in which the total count amoeba crosses (greater or equal).
