comment How does $\mathcal{A}\cup \mathcal{B}$ indicates that there is at least one augmenting path on $\mathcal{A}$?
Good. I tried to think about it (in the exam) but I didn't imagined the coloring. I tried to think that the matchings $\mathcal{A}$ and $\mathcal{B}$ were disjoint and tried to answer with this. But I noticed that when they happen to be not disjoint, I'd have problems.

comment Is it possible to solve problems about finding the number of solutions to a linear equation with the multinomial coefficient?
@Lucian No, I'm not asking how to solve it. I'm asking if it's possible to solve it using multinomial coefficients.

comment Are there two notions of flow?
Good. When I read that a flow is $f:E\to \mathbb{R}_0^+$, I tend to presume that it is the quantity of flow passing through a vertex $e$.
