Just explain 3.4More details better thank you

EXERCISE 3.4 We consider here the diffusion-reaction model of Exercise 1.6. 1. Write a conforming and a non-conforming FE schemes for this model. 2. We consider here that r is constant. Write a pseudo-algorithm for the assembly of the matrices of each scheme. Make sure that, in your algorithm, no integral remain to be computed. You will find the following quadrature rule useful: for any triangle T, denoting by 2 7 the midpoint of an edge ex of T, 9= [q(z.) Vq polynomial of degree $ 2. The model 1.6 is showing below -Au + ru = f in 1. 1 = 0 on 81, where r : 0 -+ R is a given bounded function
