3. Consider again the problem of traffic flow. In this question, We simplify the flux as F(x)=c(t)(x) so we get an advection function t=cx. and We set L=400. We set C=Sin(t/T)+1 where T is your simulation time. Then use Lax-wendorff method to see the different direction of flow for these initial conditions(the animation is needed for display). In every step t0, renormalized you current configuration to (x,t0) with =0L(x,t0)dx1. (a) (t=0,x)=0(x)={1,0,4L
