Write a program to use the C++ class GESolver that contains the routines PLUFactorization and SolvingPhase (see Canvas for code) to solve the linear system Ax = b to obtain the approximate solution . (If this is possible. A may be noninvertible. Remember to check before calling SolvingPhase) You should also compute det(A) using the triangular factorization produced by PLUFactorization. The first record of each system contains the order n of the system. The next n records each contain a row of A and the corresponding element of b. OUTPUT: For each system, write the following at the top of a new page.
