Get hold of all the important DSA concepts with the DSA Self Paced Course at a student-friendly price and become industry ...Sparse Matrix Multiplication. Given two sparse matrices A and B, return the result of AB. You may assume that A's column number is equal to B's row number. Example: A = [. [ 1, 0, 0], [-1, 0, 3] ] .

: A sparse matrix can be represented as a sequence of rows, each of which is a sequence of (column-number, value) pairs of the nonzero values in the row. Time Complexity Proposal: O(m*n + k*nB). Here k: number of non-empty elements in A. So in the worst case (dense matrix), it's O(m*n*nB)(from here) Code:
