I used find to locate the beginning and the end of the calculation to be done, but it messed up with splitting the html-source into smaller pieces.
find returns -1 if nothing was found, index returns an Error (I used Python).

I don't understand the Charset.

For example, I got this:
Charset: cwSOMlXTxChYQ8{VmvaN_g4itIUB@uP]6sr5W9Hb1pfkdLA#oD}KZyER0J7q3nj2FzG[e
Input Base: 65
Solution Base: 59
Timelimit: 3.1416 seconds
Equation: _5VJ * @_aj * YNnc * 45YD * l1g * PMb0 * x{8B * hDwp * {ucl * oPsZ * dfm3 * #WgE * 7x}3 * wUFL * ln5W * EgT{ * 9#YD * yAPu * YB0u * D3Z} * f1bN * Ad_J * sh]8
+ AuLX

The Charset has 69 characters. Why? I only need max(input_base, solution_base) = max(65,59) = 65 characters. Can I simply forget the last four characters?

If a normal charset would have been used, would c be 0? Or would e be 0?

 ```1 2 3 ``` ```print toBase10('ff', '0123456789abcdef', 16) print toBase10('1101', '0123456789abcdef', 2) print toBase10('123', '0123456789abcdef', 3)```
