How many real links are required to store a sparse matrix of 10 rows, ...
Matrix of 10 rows and 10 columns can have m axim um 1 0 x 1 0 = 100 entries. S ince only 15 non-zero entries are present, so number of real link will be 15 only.
Assuming undirected graph.

How many real links are required to store a sparse matrix of 10 rows, ...
Explanation:


To store a sparse matrix, we only need to store the non-zero elements of the matrix along with their row and column indices. This approach leads to saving space and time complexity.


Formula:


For a sparse matrix of size m x n with s non-zero elements, the number of real links required can be calculated by the formula:


Number of Real Links = s + 1


The additional 1 is required to store the size of the matrix.


Given:


Size of matrix = 10 x 10


Number of non-zero elements = 15


Calculation:


Using the formula above, we can calculate the number of real links required for the given sparse matrix as:


Number of Real Links = 15 + 1 = 16


Answer:


Therefore, the closest answer to the number of real links required to store the sparse matrix of 10 x 10 size with 15 non-zero elements is option 'A', i.e., 15.
