题目描述

New AtCoder City has an infinite grid of streets, as follows:

  • At the center of the city stands a clock tower. Let (0, 0) be the coordinates of this point.
  • A straight street, which we will call East-West Main Street, runs east-west and passes the clock tower. It corresponds to the x-axis in the two-dimensional coordinate plane.
  • There are also other infinitely many streets parallel to East-West Main Street, with a distance of 1 between them. They correspond to the lines $\ldots, y = -2, y = -1, y = 1, y = 2, \ldots$ in the two-dimensional coordinate plane.
  • A straight street, which we will call North-South Main Street, runs north-south and passes the clock tower. It corresponds to the y-axis in the two-dimensional coordinate plane.
  • There are also other infinitely many streets parallel to North-South Main Street, with a distance of 1 between them. They correspond to the lines $\ldots, x = -2, x = -1, x = 1, x = 2, \ldots$ in the two-dimensional coordinate plane.

There are N residential areas in New AtCoder City. The i-th area is located at the intersection with the coordinates (X_i, Y_i) and has a population of P_i. Each citizen in the city lives in one of these areas.

The city currently has only two railroads, stretching infinitely, one along East-West Main Street and the other along North-South Main Street.
M-kun, the mayor, thinks that they are not enough for the commuters, so he decides to choose K streets and build a railroad stretching infinitely along each of those streets.

Let the walking distance of each citizen be the distance from his/her residential area to the nearest railroad.
M-kun wants to build railroads so that the sum of the walking distances of all citizens, S, is minimized.

For each $K = 0, 1, 2, \dots, N,$ what is the minimum possible value of S after building railroads?

Constraints

  • $1 \leq N \leq 15$
  • -10 \ $000 \leq X_i \leq 10$ \ 000
  • -10 \ $000 \leq Y_i \leq 10$ \ 000
  • $1 \leq P_i \leq 1$ \ 000 \ 000
  • The locations of the N residential areas, (X_i, Y_i), are all distinct.
  • All values in input are integers.

Input

Input is given from Standard Input in the following format:

<dl> <dt>N</dt> <dt>X_1 Y_1 P_1</dt> <dt>X_2 Y_2 P_2</dt> <dd>: :
X_N Y_N P_N</dd> </dl>

Output

Print the answer in N+1 lines.
The $i-th line (i = 1, \ldots, N+1)$ should contain the minimum possible value of S after building railroads for the case K = i-1.
