I’m stuck on Stage #RK3.

Here are my logs:

```auto
remote: [compile] Moved ./.codecrafters/run.sh → ./your_program.sh
remote: [compile] Compilation successful.
remote:

remote: [tester::#RK3] expected exit code 0, got 1

```

And here’s a snippet of my code:

```auto
 elif pattern.startswith("[^") and pattern.endswith("]"):
        for char in pattern[2:-2]:
            if char not in input_line:
                continue
            else:
                excludePattern = False
                break
                #print(char)
        return excludePattern

```

Hey @cicada-581, your code should check if any character from the input is **not** in the pattern, not the other way around.

You can try running this command:

1. **o** is in **opq** , so we continue;
2. But all of **range** is **not** in **opq** , so any of them can trigger a match.

Let me know if you’d like further clarification!
