One test case??? 🤦

• The exclusion algorithm is not explained clearly enough
• The sample test with such huge inputs is unusable
• No random tests

The regex is the completely wrong solution here. It's quite slow relative to the rest of the method, by at least one order of magnatude. Which is a high price for something which is ultimately going to fail -- the start of the pattern say "match semi-colon or anything in the range ..." which means bar, open bracket & close bracket will get through, along with any whitespace character aside from a blank (such as a tab).

8 kuy pls

Ok
