Prоblem 4 (13 pоints, CCOs 2,5)Cоnsider the Gаuss-Jordаn аlgorithm with partial pivoting covered in Module 2 for non-singular linear systems with 4 equations and 4 unknowns. An AI program claims that each matrix below is the augmented matrix produced immediately after partial pivoting was performed for the second pivot position (row 2, column 2) for nine different cases. For each case: Determine whether the displayed augmented matrix could result from a correct implementation of the algorithm. Write Y for yes or N for no. If your answer is N, then either: write the augmented matrix that should have resulted from correct partial pivoting, or state that the matrix cannot be corrected because a mistake must have occurred earlier in the algorithm. The following matrices correspond to the different cases. A.
