Cybalphabit

In the new world, we also have a new system called Cybalphabit system. The system assigns points to each Latin lowercase alphabet as follows:- 'a' is assigned $2^0$ , 'b' is assigned $2^1$, 'c' $2^2$ and so on. Thus, finally 'z' is assigned $2^{25}$ points. A Cyberstring is a sequence of lowercase Latin alphabets. Now, the total score of a Cyberstring will be the sum of points of its characters.
