Introduction

Convert simple regular expressions to nondeterministic finite automaton.

Supported grammars

  • r = (s)
  • r = st
  • r = s|t
  • r = s*
  • r = s+
  • r = s?
  • r = ϵ
    (Copy this character to input if needed)

Examples

  • (a|b)*
  • (a*|b*)*
  • ((ϵ|a)b*)*
  • (a|b)*abb(a|b)*
