Regex Programming: Four Difficulties, 4000 Levels

Regex has four difficulties with 1000 levels each and ten questions per level; predict the output first, then add speed. Regex levels ask for the matched text, not the pattern; you read character classes, quantifiers, groups and lookarounds and predict the output.
