Sparse Matrix Concept Which of the following statements about sparse matrices are correct? Select all that apply: In CSR format, it is about as easy to obtain subsequent entries of a column as of a row. The CSR format is not well-suited for implementing graph traversals. Sparse matrix representations provide only reduced storage and not computation efficiency. In the CSR form of sparse matrix, the length of the array containing column indices is the same as the number of nonzeros. The inverse matrix of a sparse matrix may be dense
