Problem 2478. BLOCK x3 (Version 2)

An extension to problem 2451 ( https://www.mathworks.com/matlabcentral/cody/problems/2451-block-x3-version-1 ).

It is based on an android game - BLOCK x3. The objective is to align the 1's in the matrix using minimum movements. The valid movements are horizontal and vertical (by one step). A zero (0) indicates an empty space. Your task is to count minimum number of movements required to align the three 1's vertically or horizontally.

New challenge in this problem : There are some static elements which can not be moved and can not be included in the alignment. These elements are indicated by 2. This makes the problem a bit challenging.

Example:

Input =[0 0 0 0 0 0 0 0;
        0 0 1 0 1 0 0 0;
        0 0 0 2 1 0 0 0;
        0 0 0 0 0 0 0 0]
Output = 2;
