Pseudo code would be much appreciated

4a) Design an efficient algorithm to add 2 sparse matrices represented by ordered lists of terms consisting of row index, column index, Arithmetic value. Your design must be at least one paragraph in length. b) Simulate five steps of your algorithm of part a for the following sparse matrices a and b a = 5 500 104710811512422224931-243-5 b = 5601203511 9135224333408 453 The first pair gives the dimension of the matrix. Each following triple gives row index, column index and Arithmetic value. 4a) Design an efficient algorithm to add 2 sparse matrices represented by ordered lists of terms consisting of row index, column index, Arithmetic value.
