Consider the following version of an important algorithm that we will study later in the book. ALGORITHM GE(A[0..n 1, 0..n]) //Input: An n (n + 1) matrix A[0..n 1, 0..n] of real numbers for i 0 to n 2 do for j i + 1 to n 1 do for ki to n do A[j, k]A[j, k] A[i, k] A[j, i]/ A[i, i] a. Find the time efficiency class of this algorithm. b. What glaring inefficiency does this pseudocode contain and how can it be eliminated to speed the algorithm up?
