To find strings that do NOT contain a certain character, you can use negated character classes [^ ] that match anything NOT in brackets. For example: [^13] will match any single character that is not 1 or 3. [^1-3] will match any single character that is not 1, 2 or 3 (i.e....
as well as how you tell the system to use your regular expression pattern. Regular expression systems can be told that a "match" requires the beginning of the string to match the expression, and anything following is ignored; in that case, the third string will match the pattern....
