A10561 | Photographs (II)

The input format is the same as in the previous version, except that the first line of every question now contains three space-separated numbers $h$ , $w$ and $k$ ( $1<=h,w<=600$ , $2<=k<=16$ ) – the height (number of rows) and width (number of columns) of the photograph and the number of pieces, respectively. The number of pieces evenly divides the height, and each piece is of the same height $h/k$ .

Again, there is only one input file to be processed, and the same resources are provided to you as in the previous version (except that now you are given all input images in .bmp format, rather than the first 50).
