(Programming) Consider the following linear BVP with Dirichlet boundary conditions

- u" + 4u(x) = 0,0 < x < 1    (3)
u(0) = 1,                          (4)
u(1) = 2.                          (5)

Numerically solve this problem using finite element method on a uniform partition of the interval, with piecewise linear element functions.

Plot the solutions with different mesh sizes, and comment on the order of accuracy of the solution in L2 norm and energy norm.
