9890: ABC307 —— F - Virus 2
[Creator : ]
Description
There are $N$ rooms numbered $1$, $2$, $\ldots$, $N$, each with one person living in it, and $M$ corridors connecting two different rooms. The $i$-th corridor connects room $U_i$ and room $V_i$ with a length of $W_i$.
One day (we call this day $0$), the $K$ people living in rooms $A_1, A_2, \ldots, A_K$ got (newly) infected with a virus. Furthermore, on the $i$-th of the following $D$ days $(1\leq i\leq D)$, the infection spread as follows.
> People who were infected at the end of the night of day $(i-1)$ remained infected at the end of the night of day $i$.
> For those who were not infected, they were newly infected if and only if they were living in a room within a distance of $X_i$ from at least one room where an infected person was living at the end of the night of day $(i-1)$. Here, the distance between rooms $P$ and $Q$ is defined as the minimum possible sum of the lengths of the corridors when moving from room $P$ to room $Q$ using only corridors. If it is impossible to move from room $P$ to room $Q$ using only corridors, the distance is set to $10^{100}$.
For each $i$ ($1\leq i\leq N$), print the day on which the person living in room $i$ was newly infected. If they were not infected by the end of the night of day $D$, print $-1$.

Output
Print $N$ lines.
The $i$-th line $(1\leq i\leq N)$ should contain the day on which the person living in room $i$ was newly infected.
The $i$-th line $(1\leq i\leq N)$ should contain the day on which the person living in room $i$ was newly infected.

The infection spreads as follows.
- On the night of day 0, the person living in room 1 gets infected.
- The distances between room 1 and rooms 2,3,4 are 2,3,5, respectively. Thus, since X1=3, the people living in rooms 2 and 3 are newly infected on the night of day 1.
- The distance between rooms 3 and 4 is 2. Thus, since X2=3, the person living in room 4 also gets infected on the night of day 2.
Therefore, the people living in rooms 1,2,3,4 were newly infected on days 0,1,1,2, respectively, so print 0,1,1,2 in this order on separate lines.

Note that it is not always possible to move between any two rooms using only corridors.
