Negated class character

! Something NOT 1...6 If you use [^..] instead of [..], the class matches any character that isn't listed. For example [^1-6] matches a character that's not 1 through 6.
Regex [^x] doesn't mean "match unless there is an x". But rather "match if there is something that is not x"

^cat // find at start of the line

[^cat] // fint not ...


q[^u] matches Iraqi, Iraqian q[^u] doesn't match Qantas, because it called for a lower case q q[^u] doesn't match Iraq, because q is at the end (Newline character is not [^u]) Task
