I am trying to solve the problem Secret Code on SPOJ, and it's obviously a math problem.
The full problem
For those who are lazy to go and read, it's like this:
a0, a1, a2, ..., an - sequence of N numbers
B - a Complex Number (has both real and imaginary components)
X = a0 + a1*B + a2*(B^2) + a3*(B^3) + ... + an*(B^n)
So if you are given B and X, you should find a0, a1, ..an.
I don't know how or where to start, because not even N is known, just X and B.
The problem is not as easy as expressing a number in a base B, because B is a complex number.
How can it be solved?
