Q3. (Jacobi and Gauss-Seidel methods) Write a python code for solving a system of linear equations by Jacobi method and Gauss-Seidel method. Written in matrix form, a system of linear equations is expressed as Ax=b. 1. Define a function jacobi(A, b, x, eps, max_n), where A is the matrix A, b is the vector b, x is the initial guess of the solution, eps is the criterion for lz-norm of residual (i.e., || Xcurrent_step Xprevious_step ||2), and max_n is the maximum iteration steps allowed. This function solves the equations by Jacobi iteration. It returns the solution when || Xcurrent_step Xprevious_step ||2
