Write computer code that performs the Gauss-Seidel iterative method to solve an n x n system. Use your code to solve the following system of equations until the approximate error falls below 0.0005%. X1 + 4X3 - X4 + 2X5 13 4X1 X2 + 4X3 11X4 2Xs 12 12X1 + 4X2 - 3X3 - 3X4 + 2X5 3 3X1 3X2 -X3 + 4X4 + 12Xs 10 a) What was your final guess of the x values? b) How many iterations did your code do? c) Make sure that your code includes a check to make sure that this particular matrix will converge before it starts Gauss-Seidel. How do you know that this system will converge
