Mr.
Samir likes to play with blocks. A block has 6 sides. Left, Right, Front, Back,
Top, and Bottom. The size of a block is **(1*1*1)**.
He makes building on a **(H*W) **square
unit area. But in every coordinate, the number of blocks can be different.

Now he wants to recolor only one side
of the building. Coloring a single side of a **(1*1*1)** block requires 1 unit of cost. You need to calculate the minimum cost and help him to choose
the side of the building.

#### Input Format

The first line contains the value of ** W**
(**W** <101) and (H <101).

The next **W** lines contain H space-separated
integers.

The j^{th}^{ }integer in i^{th}^{ }line denotes the number of blocks (<101)
in **(i,j)** position.

#### Output Format

Just print the
minimum cost to paint only one side of the building (open-sided block).
