Problem Description

You want to arrange the window of your flower shop in a most pleasant way. You have FF bunches of flowers, each being of a different kind, and at least as many vases ordered in a row. The vases are glued onto the shelf and are numbered consecutively 11 through VV, where VV is the number of vases, from left to right so that the vase 11 is the leftmost, and the vase VV is the rightmost vase. The bunches are moveable and are uniquely identified by integers between 11 and FF. These id-numbers have a significance: They determine the required order of appearance of the flower bunches in the row of vases so that the bunch ii must be in a vase to the left of the vase containing bunch jj whenever i<ji < j. Suppose, for example, you have bunch of azaleas (id-number =1=1), a bunch of begonias (id-number =2=2) and a bunch of carnations (id-number =3=3). Now, all the bunches must be put into the vases keeping their id-numbers in order. The bunch of azaleas must be in a vase to the left of begonias, and the bunch of begonias must be in a vase to the left of carnations. If there are more vases than bunches of flowers then the excess will be left empty. A vase can hold only one bunch of flowers.

Each vase has a distinct characteristic (just like flowers do). Hence, putting a bunch of flowers in a vase results in a certain aesthetic value, expressed by an integer. The aesthetic values are presented in a table as shown below. Leaving a vase empty has an aesthetic value of 00. |FLOWERS|< |< |< |< |< |< | |:-----:|:--------:|:---:|:--:|:--:|:---:|:--:| | |< |VASES|< |< |< |< | | ^ |< |1\bold 1 |2\bold 2 |3\bold 3 |4\bold 4 |5\bold 5 | |Bunches|11 (Azaleas)|77 |2323|5-5|24-24|1616| |^ |22 (Begonias)|55 |2121|4-4|1010 |2323| |^ |33 (Carnations)|21-21|55 |4-4|20-20|2020|

According to the table, azaleas, for example, would look great in vase 22, but they would look awful in vase 44.

To achieve the most pleasant effect you have to maximize the sum of aesthetic values for the arrangement while keeping the required ordering of the flowers. If more than one arrangement has the maximal sum value, any one of them will be acceptable. You have to produce exactly one arrangement.

Input Format

  • The first line contains two numbers: F,VF, V.
  • The following FF lines: Each of these lines contains VV integers, so that Ai,jA_{i, j} is given as the jj-th number on the (i+1)(i+1)-st line of the input file.

Output Format

  • The first line will contain the sum of aesthetic values for your arrangement.
  • The second line must present the arrangement as a list of FF numbers, so that the kk-th number on this line identifies the vase in which the bunch kk is put.

ASSUMPTIONS

  • 1F1001 \leq F \leq 100 where FF is the number of the bunches of flowers. The bunches are numbered 11 through FF.
  • FV100F \leq V \leq 100 where VV is the number of vases.
  • 50Ai,j50-50 \leq A_{i, j} \leq 50 where Ai,jA_{i, j} is the aesthetic value obtained by putting the flower bunch ii into the vase jj.
