WebRepresenting a sparse matrix by a 2D array leads to the wastage of lots of memory. This is because zeroes in the matrix are of no use, so storing zeroes with non-zero elements is wastage of memory. To avoid such wastage, we can store only non-zero elements. If we store only non-zero elements, it reduces the traversal time and the storage space. http://londonderryonline.co.uk/declaration-and-initialization-of-two-dimensional-array-in-c
