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. WebHá 15 horas · Hello i am currently writing a program to emulate bouldering in real life, where there is a Wall ADT where you can store certain rocks on the wall which is represented basically as a 2d matrix.
