(a): (x.x) (b): (x.x) y (c): (xy.xz) y

(d):(x.x) (y.yx)

For each of the expressions, show what it reduces to. (If an expression doesn't reduce any further, just write the expression as-is as your answer.)

Hint: You are allowed to, and probably should, use an interpreter such as the one at http://jacksongl.github.io/files/demo/lambda/
