Quantization Problem

When entering some analog data into a computer, this information must be quantized. Quantization transforms each measured value x to some other value l(x) selected from the predefined set L of levels. Sometimes to reduce the influence of the levels set to the information, the group of levels sets Li is used. The number of levels sets is usually chosen to be the power of 2.

When using the number of levels sets, some additional information should be used to specify which set was used for each quantization. However, providing this information may be too expensive - the better solution would be to choose more levels and use one set. To avoid the specification of the quantization set, the following technique is used. Suppose that n values x1, x2, ... , xn are to be quantized and the group of m = 2p levels sets {Li} (i = 0, 1, ... , m-1) each of size s = 2q is used to quantize it. After quantization xj is replaced with some number lj in Lf(j). Instead of sending lj, its ordinal number in Lf(j) is usually sent, let kj be the ordinal number of lj in Lf(j) (levels are numbered starting with 0). Take p least significant bits of kj and say that the number kj&(2p - 1) is the number of the levels set that will be used for next quantization, that is f(j + 1) = kj&(2p - 1).

Since the least significant bits of kj are usually distributed quite randomly, the sets used for quantization change often and weakly depend on values of quantized data, thus this technique provides the good way to perform the quantization.

Usually to perform the quantization the closest to the value level of the levels set is chosen. However, using the technique described, sometimes it pays off to choose not the optimal level, but some other one, the ordinal number of which has other least significant bits, thus choosing another levels set for next measure and providing better approximation of quantized values in the future. Let us call the deviation of quantization the value |x1-l1| + |x2-l2| + ... + |xn-ln|. Your task is given measures and levels sets to choose quantized value for each measure in such a way, that the deviation of quantization is minimal possible.

The first value is always quantized using set L0.


This problem contains multiple test cases!

The first line of a multiple input is an integer N, then a blank line followed by N input blocks. Each input block is in the format indicated in the problem description. There is a blank line between input blocks.

The output format consists of N output blocks. There is a blank line between output blocks.


Input

The first line of the input file contains n (1 <= n <= 1000). The second line contains n integer numbers xi ranging from 1 to 106. The next line contains m and s (1 <= m <= 128, m <= s <= 128). Next m lines contain s integer numbers each - levels of the quantization sets given in increasing order for each set, all levels satisfy 1 <= level <= 106.


Output

First output the minimal possible deviation of the quantization. Then output n integer numbers in range from 0 to s - 1. For each input value output the number of the level in the corresponding levels set (kj) used for this number to achieve the quantization required.
