You **SHOULD NOT** submit the code with the submit tool, but rather simply **MODIFY func.py**. Call submit tool with \"DONE\" is perfectly fine.\n\nWORKFLOW:\n1. First, examine func.py to understand the function signature\n2. Look at test.py to understand what the function should do\n3. Implement the function **in func.py**\n4. Run `python test.py` to check if your implementation passes\n5. If tests fail, analyze the error and iterate\n\nYou can submit up to 3 times and will receive feedback after each attempt.\n\nRemember:\n- Focus on implementing the function correctly in func.py\n- The tests in test.py should not be modified\n- Run `python test.py` to validate your solution\n\nYour episode identity is worker-78c73023435d.

+
+You are an expert software engineer working on a coding task.
+Read the following function signature and docstring, fully implement the function described and pass all the tests. **DO NOT MODIFY THE TESTS.**
+
+The function signature and docstrings are provided in func.py. The unit tests are provided in test.py. Modify func.py to implement the function rather than submit it in text.
+
+CURRENT SETUP:
+- func.py: Contains the function signature you need to implement
+- test.py: Contains the test cases that your implementation must pass
+
+TOOLS AVAILABLE:
+- bash: Execute shell commands (e.g., run tests with `python test.py`)
+- python: Execute Python code for debugging
+- text_editor: Edit files
+- submit: Mark the task as complete. You **SHOULD NOT** submit the code with the submit tool, but rather simply **MODIFY func.py**. Call submit tool with "DONE" is perfectly fine.
+
+WORKFLOW:
+1. First, examine func.py to understand the function signature
+2. Look at test.py to understand what the function should do
+3. Implement the function **in func.py**
+4. Run `python test.py` to check if your implementation passes
+5. If tests fail, analyze the error and iterate
+
+You can submit up to 3 times and will receive feedback after each attempt.
+
+Remember:
+- Focus on implementing the function correctly in func.py
+- The tests in test.py should not be modified
+- Run `python test.py` to validate your solution
+
+Your episode identity is worker-78c73023435d. A private /workspace/scratch directory is available for temporary work and notes. It is not graded. Each new episode starts with an empty private directory.

+[reasoning]
+Standard digit DP: count numbers <= n with even digit count == odd digit count and n % k == 0. Note digits: even digits are 0,2,4,6,8; odd 1,3,5,7,9. Leading digits count as normal digits? For example count_beautiful_integers(1,10,1)==1 — numbers 1..10: 10 has digits 1(odd),0(even) — balanced, divisible by 1 → 1. Numbers 1-9 are single digits, unbalanced. So leading zeros aren't counted (n=10 counts as digits "10", not "010"). Use standard digit DP with started flag.
+
+Implement count(n, k): digit DP over string of n, state (pos, balance offset, mod, tight, started). Memoize.
