writing a c++ program for question

Part B [60] Part A was to write and test a class that implemented the ADT Matrix using the built-in two-dimensional array data structure. This part requires you to implement the same operations using another underlying data structure. This new structure is appropriate for sparse matrices: matrices with many zero elements. You are to use the same class specification as your interface, changing only the private data members. values should be SortedType in this implementation. Sparse Matrixes A sparse matrix is one where there are many zero elements. For example, a matrix A is as follows: A- 3 0405 0 0 2 0 1 1 0 0 0 2 Page 2 of3 Matrix A has 4 rows and 5 columns. Of the 20 places in the matrix, 13 of them are zero. We represent this matrix as a sorted list of triples as shown below. The matrix operation:s become operations on lists. ow column alue 4 Processing Notes The list of values should be kept ordered by column within rows. The test plan for an array-based implementation should have been based on the shape of the matrices. A test plan for a list implementation should include cases dealing with the length of the list (empty, only one item, etc.).
