Great kata! Very original. Enjoyed solving it. Only 189 completions in 7 years? Come on codewarriors, give it a go. This one deserves more attention.

Why returning
std::vector<int>in C++, if there is a built-instd::complex<int>?It's the same in Python.
All three are bad, but not all questions have a good answer ..
Sample tests and initial solution are broken.
using namespace std;in it. That shouldn't be a case.using namespace std;being in the solution. That shouldn't be a case either.I am pretty new to coding and do not really know what to do with a problem that is basically pure maths like this. What does that last block mean [a, b] = a+b*i? What is my output actually supposed to look like? If I am given a string with some number like 101 (one hundred one) and...is that not ALREADY in base 10 form? I am very confused. Could I have some clarification? Thanks!
Do you know what are number systems with different bases? Like binary, octal, decimal, hexadecimal?
Do you know what are imaginary numbers, complex numbers, and imaginary unit
i?There are two ways to solve this kind of problems:
It was like SUPER late when I attempted the problem and I was not at my best. I know all about base-types and numerical expressions. I was just being stupid. I got some help via discord and ended up getting to a solution that, while clunky, helped to teach me some fundamentals. I put an EXTENSIVE comment suite in the solution that explains my data stream for a sample input. Thanks!
10010 in base i would be:
1*i^4 + 0 * i^3 + 0 * i^2 + 1 * i^1 + 0 * i^0 = 1 + -i = 1-iThis should be
1 + i,1 * i^1 = inot-iFixed

Description, second code block: why are you going on into negative exponents? This would be applicable to some fixed point situation, but not here, is it? It's inconsistent with all other examples and tests.
Third code block:
-1 + 0 + 1does not equal2. The example test has this correct though.Fixed, thanks!

Thank you, fixed! I'm still learning how all this works so I didn't even realize
