    Method
    Description
    static int[][][]
    eraseDuplicates(int[][][] data)
    Erase duplicates in a array of matrices The input matrix stays unchanged
    static int[][]
    eraseEmptySpace(int[][] data)
    Erase rows and columns that contain only zeros
    static int[][]
    horizontalFlip(int[][] data)
    Flip the matrix horizontally It makes a copy, the input matrix stays unchanged
    static boolean
    isEqual(int[][] data1, int[][] data2)
    Check if two matrices are equal Assume they have the same size
    static boolean
    isEqualRecursion(int[][] data1, int[][] data2, int row, int column)
     
    static void
    main(String[] args)
     
    static int[][]
    makeBigger(int[][] data, int size)
    Expands a smaller than size*size matrix to a size*size matrix It makes a copy, the input matrix stays unchanged Assume that the input is smaller than size!!
    static void
    makeDatabase()
    Make the database, created based on the pentomino's pieces defined in basicDatabase
    static int[][]
    moveToAbove(int[][] data)
    Move matrix to the left above corner Does not make a copy!
    static int[][]
    rotate(int[][] data, int rotation)
    Rotate the matrix x times over 90 degrees Assume that the matrix is a square! It does not make a copy, so the return matrix does not have to be used
    static int[][]
    verticalFlip(int[][] data)
    Flip the matrix vertically It makes a copy, the input matrix stays unchanged
