Block Town
Children like playing with blocks (cube wooden bricks). They usually build
high towers, but small Johny dreams of different plans. He is going to build a
big town. His daddy has bought him a rectangular table; its width is K blocks
and its length is L blocks exactly. Johny decided to project a plan of such a
town before he starts building the town itself. He has drawn a square-shaped
network on the table consisting of KxL squares. He wants to place the towers
consisting of one or more blocks on some of the squares of the network drawn;
the remaining squares will be empty. Because of the table being so large, Johny is not
going to plan exactly for every square how many blocks he will put on it. He
only wants to decide about front and right sight shapes of his town. He drew
these two views (two-dimensional projections of the planned town) on a
paper. You can see an example of these drawings and the adequate town made of
wooden bricks in the pictures:
Johny's daddy is afraid they don't have enough blocks to finish building
Johny's planned town. You are asked for writing a program to compute the
minimal and maximal amount of blocks with which a town corresponding to
Johny's plans can be built. Moreover the program can decide about the
possibility of building a town satisfying the views.
Input:
The first line of input file TOWN.IN contains two positive integers K, L --
the width and the length of the table (expressed as numbers of
bricks). Neither the width nor the length of the table is greater than 100000
bricks. The following lines of the input file contain the description of the
front view of the town. The description consists of a series of heights of
visible buildings on each square from the left to the right (the height is
measured by the number of the blocks, too). There is only one number on each
line, i.e. the number of the lines with the front view description of the town
equals K -- the width of the table. Similarly the next L lines of the input
file contain the right sight view of the town. The heights of the wooden block
towers are now specified from the front line to the back line. You may suppose
there is no building in the town with height exceeding 5000 blocks. The
maximal number of blocks needed for building the entire town does not exceed
2000000000.
Output:
Output file TOWN.OUT contains only one line. If it is not possible to build a
town with the front and right sight views given, only a text `No solution.' is
written there. In the other case two numbers will be written on the line and
separated by a single space. The first one is the minimal and the second one
is the maximal amount of blocks small Johny can use to build his town in
accordance with his project.
