Flatland government is building a new highway that will be used to transport
weapons from its main weapon plant to the frontline in order to support the undergoing military
operation against its neighbor country Edgeland. Highway is a straight line
and there are `n` construction teams working at some points on it.
During last days the threat of a nuclear attack from Edgeland has significantly increased.
Therefore the construction office has decided to develop an evacuation plan
for the construction teams in case of a nuclear attack. There are `m` shelters located
near the constructed highway. This evacuation plan must assign each team to a shelter
that it should use in case of an attack.
Each shelter entrance must be securely locked from the inside to prevent any damage to the shelter itself.
So, for each shelter there must be some team that goes to this shelter in case of an attack.
The office must also supply fuel to each team, so that it can
drive to its assigned shelter in case of an attack. The amount of fuel that is needed is proportional to the distance
from the team's location to the assigned shelter. To minimize evacuation costs, the
office would like to create a plan that minimizes the total fuel needed.
Your task is to help them develop such a plan.
The first line of the input file contains `n` — the number of construction teams (`1\ ≤\ n\ ≤\ 4000`).
The second line contains `n` integer numbers — the locations of the teams.
Each team's location is a positive integer not exceeding `10^9`, all team locations are different.
The third line of the input file contains `m` — the number of shelters (`1\ ≤\ m\ ≤\ n`).
The fourth line contains `m` integer numbers — the locations of the shelters.
Each shelter's location is a positive integer not exceeding `10^9`, all shelter locations are different.
The amount of fuel that needs to be supplied to a team at location `x` that goes to a shelter at location `y` is equal
to `|x\ -\ y|`.
The first line of the output file must contain `z` — the total amount of fuel needed.
The second line must contain `n` integer numbers: for each team output the number of the
shelter that it should be assigned to. Shelters are numbered from 1 to `m` in the order they are
listed in the input file.
