(setq leetcode-directory "~/leetcode")
```

If you want to have some code before your solution, which may make auto-completion work better but shouldn't been submitted, you can customize `leetcode-ignore-region` to ignore lines in your code. For example, suppose you have a `common.h` and some custom definations, and `leetcode-ignore-region` is set to `'("" "// start code")`, only code below `// start code` will be submitted:

```c++
#include "common.h"
... your custom definations ...
// start code

class Solution {
......
```

# Work with Org Mode

`leetcode-show-problem-by-slug` will let you put to org files with a link in this format to show the question after the *leetcode* buffer is load like [elisp:(leetcode-show-problem-by-slug (leetcode--slugify-title "ZigZag Conversion"))]
