Given the graph below 1 of 2 a. (20 points) Give the adjacency-list and adjacency-matrix representation:s b. (5 points) Give one advantage that each representation has over the other 4. In this problem you will develop algorithms to multiply two n-digit numbers x and y where n is very large and thus must be represented using a data structure such as a list or aray where each element holds a single digit. Suppose that in one instruction you can only multiply, add or subtract two 1-digit numbers. Your task is to design an algorithm to multiply two n digit numbers using only basic arithmetic operations on 1 digit numbers (which can be performed as a table look-up).
