Define the language (no proof required). But define the language formally rather than informally, using a set and Kleene star as in the below definitions.

(a) {w {0, 1} : w contains the substring 010}.

(b) {w {0, 1} : w does not contain the substring 010}.

(c) {w {0, 1} : w ends with the substring 010}.

(d) {w {0, 1} : w has length 3 and its third symbol is 1}.
