Sample Topological Spaces: X,t,G,F

[cothranaimeel]

Think of a very simple topological space in the following examples:

a) (X,t) is a topological space, G is open, and G Does not equal Int(Clo(G))?

b) (X,t) is a topological space, F is closed, and F Does not equal Clo(Int (F))?

thanks for helping
