Write a .patch file to stdout that will fix the bug in this tokenizer. Still keep the new file name the same after patching. I'll evaluate you based on my ability to do - echo [your patch] > fix.patch - patch < fix.patch - python3 run_tokenizer.py Here is the entirety of run_tokenizer.py:

Output

To create a patch that fixes the bug in the provided tokenizer, we first need to identify the issue. The current implementation of the `Tokenizer` class uses a regular expression to tokenize an input string, but it does not correctly handle the case when there are multiple operators in sequence or when there are spaces in the input string. To address this, we'll modify the regular expression to include whitespace handling and ensure that the tokens are created correctly. Here's the patch:

Here's a patch that addresses a bug in the `Tokenizer` class. The issue arises from the way the regular expression handles operators and functions. The current regex captures operators correctly but does not properly handle cases where functions like `sin` and `cos` are directly followed by parentheses. To fix this, we can modify the regex to capture functions correctly and ensure that operators are only matched when they are not part of a function call. Here's the patch:

Output

To address the bug in the provided tokenizer, we need to modify the regular expression used in the `re.findall` method. The current regex pattern is not correctly capturing operators as separate tokens because of the way the parentheses are set up. The capturing group `(...)` is causing the operators not to appear in the token list as independent tokens. Here's how to fix this issue: 1. Use a non-capturing group for the operators. 2. Remove the parentheses around the operators, so they are treated as separate tokens. Here's the patch file content that makes these adjustments:
