Problem Statement
翻译中…
An SNS has $N$ users - User $1$, User $2$, $\cdots$, User $N$.
翻译中…
Between these $N$ users, there are some relationships - $M$ friendships and $K$ blockships.
翻译中…
For each $i = 1, 2, \cdots, M$, there is a bidirectional friendship between User $A_i$ and User $B_i$.
翻译中…
For each $i = 1, 2, \cdots, K$, there is a bidirectional blockship between User $C_i$ and User $D_i$.
翻译中…
We define User $a$ to be a friend candidate for User $b$ when all of the following four conditions are satisfied:
翻译中…
$a \neq b$.- There is not a friendship between User
$a$and User$b$. - There is not a blockship between User
$a$and User$b$. - There exists a sequence
$c_0, c_1, c_2, \cdots, c_L$consisting of integers between$1$and$N$(inclusive) such that$c_0 = a$,$c_L = b$, and there is a friendship between User$c_i$and$c_{i+1}$for each$i = 0, 1, \cdots, L - 1$.

For each user $i = 1, 2, ... N$, how many friend candidates does it have?

There is a friendship between User $2$ and $3$, and between $3$ and $4$. Also, there is no friendship or blockship between User $2$ and $4$. Thus, User $4$ is a friend candidate for User $2$.
However, neither User $1$ or $3$ is a friend candidate for User $2$, so User $2$ has one friend candidate.
