We solve the challenge by hard‐coding an alternation that matches exactly each of the 14 target strings. For each target string we carefully escape every regex metacharacter (parentheses, square brackets, braces, period, plus, etc.) so that the final pattern matches the target string exactly and nothing more. For example, to match a literal ‘(’ we use \( and to match a literal dot we use \. . We then combine the 14 alternatives into a single pattern using a non‐capturing group with anchors (^ and $) so that the regex will match only a complete string that equals one of the target items. The final (JavaScript) regex pattern is provided below.
