Problem Statement
There is a city whose shape is a $1{,}000 \times 1{,}000$ square. The city has a big river, which flows from the north to the south and separates the city into just two parts: the west and the east.
Recently, the city mayor has decided to build a highway from a point $s$ on the west part to a point $t$ on the east part. A highway consists of a bridge on the river, and two roads: one of the roads connects $s$ and the west end of the bridge, and the other one connects $t$ and the east end of the bridge. Note that each road doesn’t have to be a straight line, but the intersection length with the river must be zero.
In order to cut building costs, the mayor intends to build a highway satisfying the following conditions:
- Since bridge will cost more than roads, at first the length of a bridge connecting the east part and the west part must be as short as possible.
- Under the above condition, the sum of the length of two roads is minimum.
Your task is to write a program computing the total length of a highway satisfying the above conditions.
Input
The input consists of a single test case. The test case is formatted as follows.
$sx$ $sy$ $tx$ $ty$
$N$
$wx_1$ $wy_1$
:
:
$wx_N$ $wy_N$
$M$
$ex_1$ $ey_1$
:
:
$ex_M$ $ey_M$
At first, we refer to a point on the city by a coordinate $(x, y)$: the distance from the west side is $x$ and the distance from the north side is $y$.
The first line contains four integers $sx$, $sy$, $tx$, and $ty$ ($0 \leq sx, sy, tx, ty \leq 1{,}000$): points $s$ and $t$ are located at $(sx, sy)$ and $(tx, ty)$ respectively. The next line contains an integer $N$ ($2 \leq N \leq 20$), where $N$ is the number of points composing the west riverside. Each of the following $N$ lines contains two integers $wx_i$ and $wy_i$ ($0 \leq wx_i, wy_i \leq 1{,}000$): the coordinate of the $i$-th point of the west riverside is $(wx_i, wy_i)$. The west riverside is a polygonal line obtained by connecting the segments between $(wx_i, wy_i)$ and $(wx_{i+1}, wy_{i+1})$ for all $1 \leq i \leq N-1$. The next line contains an integer $M$ ($2 \leq M \leq 20$), where $M$ is the number of points composing the east riverside. Each of the following $M$ lines contains two integers $ex_i$ and $ey_i$ ($0 \leq ex_i, ey_i \leq 1{,}000$): the coordinate of the $i$-th point of the east riverside is $(ex_i, ey_i)$. The east riverside is a polygonal line obtained by connecting the segments between $(ex_i, ey_i)$ and $(ex_{i+1}, ey_{i+1})$ for all $1 \leq i \leq M-1$.
You can assume that test cases are under the following conditions.
- $wy_1$ and $ey_1$ must be 0, and $wy_N$ and $ey_M$ must be $1{,}000$.
- Each polygonal line has no self-intersection.
- Two polygonal lines representing the west and the east riverside have no cross point.
- A point $s$ must be on the west part of the city. More precisely, $s$ must be on the region surrounded by the square side of the city and the polygonal line of the west riverside and not containing the east riverside points.
- A point $t$ must be on the east part of the city. More precisely, $t$ must be on the region surrounded by the square side of the city and the polygonal line of the east riverside and not containing the west riverside points.
- Each polygonal line intersects with the square only at the two end points. In other words, $0 < wx_i, wy_i <1{,}000$ holds for $2 \leq i \leq N-1$ and $0 < ex_i, ey_i <1{,}000$ holds for $2 \leq i \leq M-1$.
Output
Output single-space separated two numbers in a line: the length of a bridge and the total length of a highway (i.e. a bridge and two roads) satisfying the above mayor's demand. The output can contain an absolute or a relative error no more than $10^{-8}$.
