The best night ever in the world has come! It's 8 p.m. of December 24th, yes,
the night of Cristmas Eve. Santa Clause comes to a silent city with ringing
bells. Overtaking north wind, from a sleigh a reindeer pulls she shoot
presents to soxes hanged near windows for children.
The sleigh she is on departs from a big christmas tree on the fringe of the
city. Miracle power that the christmas tree spread over the sky like a web and
form a paths that the sleigh can go on. Since the paths with thicker miracle
power is easier to go, these paths can be expressed as undirected weighted
graph.
Derivering the present is very strict about time. When it begins dawning the
miracle power rapidly weakens and Santa Clause can not continue derivering any
more. Her pride as a Santa Clause never excuses such a thing, so she have to
finish derivering before dawning.
The sleigh a reindeer pulls departs from christmas tree (which corresponds to
0th node), and go across the city to the opposite fringe (_n_ -1 th node)
along the shortest path. Santa Clause create presents from the miracle power
and shoot them from the sleigh the reindeer pulls at his full power. If there
are two or more shortest paths, the reindeer selects one of all shortest paths
with equal probability and go along it.
By the way, in this city there are _p_ children that wish to see Santa Clause
and are looking up the starlit sky from their home. Above the _i_ -th child's
home there is a cross point of the miracle power that corresponds to
_c_[_i_]-th node of the graph. The child can see Santa Clause if (and only if)
Santa Clause go through the node.
Please find the probability that each child can see Santa Clause. | [{"input": "2 1\n 0 1 2\n 1 2 3\n 1\n 4 5 2\n 0 1 1\n 0 2 1\n 1 2 1\n 1 3 1\n 2 3 1\n 1\n 2\n 0 0 0", "output": ".00000000\n \n 0.50000000\n 0.50000000"}] |

Nuske has a grid with N rows and M columns of squares. The rows are numbered 1
through N from top to bottom, and the columns are numbered 1 through M from
left to right. Each square in the grid is painted in either blue or white. If
S_{i,j} is 1, the square at the i-th row and j-th column is blue; if S_{i,j}
is 0, the square is white. For every pair of two blue square a and b, there is
at most one path that starts from a, repeatedly proceeds to an adjacent (side
by side) blue square and finally reaches b, without traversing the same square
more than once.
Phantom Thnook, Nuske's eternal rival, gives Q queries to Nuske. The i-th
query consists of four integers x_{i,1}, y_{i,1}, x_{i,2} and y_{i,2} and asks
him the following: when the rectangular region of the grid bounded by (and
including) the x_{i,1}-th row, x_{i,2}-th row, y_{i,1}-th column and
y_{i,2}-th column is cut out, how many connected components consisting of blue
squares there are in the region?

Nuske has a grid with N rows and M columns of squares. The rows are numbered 1
through N from top to bottom, and the columns are numbered 1 through M from
left to right. Each square in the grid is painted in either blue or white. If
S_{i,j} is 1, the square at the i-th row and j-th column is blue; if S_{i,j}
is 0, the square is white. For every pair of two blue square a and b, there is
at most one path that starts from a, repeatedly proceeds to an adjacent (side
by side) blue square and finally reaches b, without traversing the same square
more than once.
Phantom Thnook, Nuske's eternal rival, gives Q queries to Nuske. The i-th
query consists of four integers x_{i,1}, y_{i,1}, x_{i,2} and y_{i,2} and asks
him the following: when the rectangular region of the grid bounded by (and
including) the x_{i,1}-th row, x_{i,2}-th row, y_{i,1}-th column and
y_{i,2}-th column is cut out, how many connected components consisting of blue
squares there are in the region?

Nuske has a grid with N rows and M columns of squares. The rows are numbered 1
through N from top to bottom, and the columns are numbered 1 through M from
left to right. Each square in the grid is painted in either blue or white. If
S_{i,j} is 1, the square at the i-th row and j-th column is blue; if S_{i,j}
is 0, the square is white. For every pair of two blue square a and b, there is
at most one path that starts from a, repeatedly proceeds to an adjacent (side
by side) blue square and finally reaches b, without traversing the same square
more than once.

| Statement
There are 2N balls, N white and N black, arranged in a row. The integers from
1 through N are written on the white balls, one on each ball, and they are
also written on the black balls, one on each ball. The integer written on the
i-th ball from the left (1 ≤ i ≤ 2N) is a_i, and the color of this ball is
represented by a letter c_i. c_i = `W` represents the ball is white; c_i = `B`
represents the ball is black.
Takahashi the human wants to achieve the following objective:
* For every pair of integers (i,j) such that 1 ≤ i < j ≤ N, the white ball with i written on it is to the left of the white ball with j written on it.
* For every pair of integers (i,j) such that 1 ≤ i < j ≤ N, the black ball with i written on it is to the left of the black ball with j written on it.
In order to achieve this, he can perform the following operation:
* Swap two adjacent balls.
