Week 7: Array and Matrices

Write the class “DoubleLinkedSparseMatrix”.
DoubleLinkedSparseMatrix 클래스를 만드세요.

The class has two kinds of chains: row chains and column chains.
이 클래스는 두종류의 체인을 갖고 있어요. 행과, 열.

Each row has a row chain that consists of elements at the same row.
각 열에는 같은 열에 있는 인자를 저장하는 열체인을 갖고있어요.

Similarly, each column has a column chain.
비슷하게, 각 행은 행체인을 갖고있어요.

Naturally, an element is linked in both a row chain and a column chain at the same time.
당연히 각 인자는 열체인과 행체인에 연결되어 있어요.
The class must provide following methods other than constructors.
이 클래스는 아래에 있는 것들을 갖고있어야 되요.

A) Int insert(int row, int col, Object element)
삽입.
B) Object remove(int row, int col)
제거
C) Void transpose()
행-열변환
D) Object get(int row, int col)
겟
E) Iterator getRowIterator(int row)
열 Iterator.
F) Iterator getColumnIterator(in col)
행 Iterator.

You have to write both interator classes, “SparseMatrixRowIterator” and “SparseMatrixColumnIterator” based on your “DoubleLinkedSparseMatrix”.
그러니까 2개의 iterator클래스도 만들어야되죠. SparseMatrixRowIterator랑 SparseMatrixColumnIterator

A row iterator iterates the elements in a row sequentially (from the one with the smallest column).
SparseMatrixRowIterator녀석은 행을 따라 움직여야 되고,
A column iterator iterates the elements in a column one by one.
SparseMatrixColumnIterator녀석은 열을 따라 움직여야 되요.

You must do your homework solely, not with any friends.
과제는 혼자하세요,, 친구랑 같이 하지 말고....
