If n ≥ 1 is an integer and w = a1a2 . . . an is a string, then for any i
with 0 ≤ i < n, the string a1a2 . . . ai
is called a proper prefix of w. (If i = 0,
then a1a2 . . . ai = ǫ.)
For any language L, we define MIN(L) to be the language
MIN(L) = {w ∈ L : no proper prefix of w belongs to L}.
Prove the following claim: If L is a regular language, then MIN(L) is regular
as well.
