+Domain name ideas
+Problem statement
+Your company is launching a new product and asks you to come up with some domain name ideas. Each domain name you propose must match a pattern chosen by the branding team. A pattern is a regular expression using lowercase letters and brackets only.
+
+For example, b[aeiou]g means that the domain name must start with b, end with g, and contain a vowel in between. bag beg big bog bug are the only five domain names that match the pattern.
+
+Furthermore, generated domain names cannot contain the same character repeated three or more times consecutively (e.g., good is valid, but sooogood is not good).
+
+The input file contains a list of patterns, one pattern per line. For each pattern, output a space-separated, lexicographically sorted list of names that match the pattern on a single line ending with a "\n".
+
+If more than 100 possibilities exist, list the 100 lexicographically smallest names only. If none exists, output an empty line.
+
+Constraints
+Each pattern is guaranteed to be a valid regular expression, between 1 and 200 characters (inclusive).
+Each pattern may contain multiple bracket pairs but not any other regular expression metacharacters such as +, ^, ?, etc.
+Each bracket pair is guaranteed to contain at least one and at most 26 characters without duplicates.
+Sample input
+b[aeiou]g
+g[et]a[job]
+Expected output
+bag beg big bog bug
+geab geaj geao gtab gtaj gtao

+### 🤖 Cursor Assistant
+
+I'll solve this domain name pattern matching problem. Let me create a Python solution that:
+1. Parses patterns with brackets
+2. Generates all matching combinations
+3. Filters out names with 3+ consecutive repeated characters
+4. Returns up to 100 lexicographically sorted results
+
+---
+
+### 🤖 Cursor Assistant
+
+Now let me create a test file with the provided input and run the solution:
+
+---
+
+### 🤖 Cursor Assistant
+
+Let me test the solution with the sample input first to verify it works correctly:
+
+---
+
+### 🤖 Cursor Assistant
+
+Good! The sample output is correct. Now let me optimize the solution to handle larger patterns more efficiently, as some patterns might generate too many combinations:
+
+---
+
+### 🤖 Cursor Assistant
+
+Perfect! The solution is working correctly. Let me verify a few specific test cases to ensure edge cases are handled properly:
+
+---
+
+### 🤖 Cursor Assistant
+
+Excellent! All tests pass. Now let me create a README and verify the complete solution:
+
+---
+
+### 🤖 Cursor Assistant
+
+Let me verify the output format matches the expected output exactly:
+
+---
+
+### 🤖 Cursor Assistant
+
+Perfect! The output matches the expected results exactly. Let me create a concise summary:
+
+---
+
+### 🤖 Cursor Assistant
+
+Let me create one final validation showing key test cases work correctly:
+
+---
+
+### 🤖 Cursor Assistant
+
+I see a small issue with the validation. Let me check what's happening with the `[aaa]` pattern:
