First, create the datatype Bool, having the values T and F.

Then, write these functions in SML:

myor (p: Bool, q: Bool) This function should return the same value as p or q.

myand (p: Bool, q: Bool) This function should return the same value as p and q.

mynot (p: Bool) This function should the same value as not p.

Do not use these pieces of SML: andalso, orelse, built-in boolean datatype.
