You ask the submarine to determine the best route out of the deep-sea cave, but it only replies:

Syntax error in navigation subsystem on line: all of them
|
||||
```
|
||||
|
||||
**All of them?!** The damage is worse than you thought. You bring up a copy of the navigation subsystem (your puzzle input).
|
||||
|
||||
The navigation subsystem syntax is made of several lines containing chunks. There are one or more **chunks** on each line, and chunks contain zero or more other chunks. Adjacent chunks are not separated by any delimiter; if one chunk stops, the next chunk (if any) can immediately start. Every chunk must **open** and **close** with one of four legal pairs of matching characters:
|
||||
|
||||
- If a chunk opens with `(`, it must close with `)`.
|
||||
- If a chunk opens with `[`, it must close with `]`.
|
||||
- If a chunk opens with `{`, it must close with `}`.
|
||||
- If a chunk opens with `<`, it must close with `>`.
|
||||
|
||||
So, `()` is a legal chunk that contains no other chunks, as is `[]`. More complex but valid chunks include `([])`, `{()()()}`, `<([{}])>`, `[<>({}){}[([])<>]]`, and even `(((((((((())))))))))`.
|
||||
|
||||
Some lines are **incomplete**, but others are **corrupted**. Find and discard the corrupted lines first.
|
||||
|
||||
A corrupted line is one where a chunk **closes with the wrong character** - that is, where the characters it opens and closes with do not form one of the four legal pairs listed above.
|
||||
|
||||
Examples of corrupted chunks include `(]`, `{()()()>`, `(((()))}`, and `<([]){()}[{}])`. Such a chunk can appear anywhere within a line, and its presence causes the whole line to be considered corrupted.
|
||||
|
||||
For example, consider the following navigation subsystem:
|
||||
|
||||
```
|
||||
[({(<(())[]>[[{[]{<()<>>
|
||||
[(()[<>])]({[<{<<[]>>(
|
||||
{([(<{}[<>[]}>{[]{[(<()>
|
||||
(((({<>}<{<{<>}{[]{[]{}
|
||||
[[<[([]))<([[{}[[()]]]
|
||||
[{[{({}]{}}([{[{{{}}([]
|
||||
{<[[]]>}<{[{[{[]{()[[[]
|
||||
[<(<(<(<{}))><([]([]()
|
||||
<{([([[(<>()){}]>(<<{{
|
||||
<{([{{}}[<[[[<>{}]]]>[]]
|
||||
```
|
||||
|
||||
Some of the lines aren't corrupted, just incomplete; you can ignore these lines for now. The remaining five lines are corrupted:
|
||||
|
||||
- `{([(<{}[<>[]}>{[]{[(<()>` - Expected `]`, but found `}` instead.
|
||||
- `[[<[([]))<([[{}[[()]]]` - Expected `]`, but found `)` instead.
|
||||
- `[{[{({}]{}}([{[{{{}}([]` - Expected `)`, but found `]` instead.
|
||||
- `[<(<(<(<{}))><([]([]()` - Expected `>`, but found `)` instead.
|
||||
- `<{([([[(<>()){}]>(<<{{` - Expected `]`, but found `>` instead.
|
||||
|
||||
Stop at the first incorrect closing character on each corrupted line.
|
||||
|
||||
Did you know that syntax checkers actually have contests to see who can get the high score for syntax errors in a file? It's true! To calculate the syntax error score for a line, take the **first illegal character** on the line and look it up in the following table:
|
||||
|
||||
- `)`: `3` points.
|
||||
- `]`: `57` points.
|
||||
- `}`: `1197` points.
|
||||
- `>`: `25137` points.
|
||||
|
||||
In the above example, an illegal `)` was found twice (`2*3 = 6` points), an illegal ] was found once (`57` points), an illegal } was found once (`1197` points), and an illegal > was found once (`25137` points). So, the total syntax error score for this file is `6+57+1197+25137` = **`26397`** points!
|
||||
|
||||
Find the first illegal character in each corrupted line of the navigation subsystem. **What is the total syntax error score for those errors?**
|
||||
|
||||
## Part 2
|
||||
|
||||
Now, discard the corrupted lines. The remaining lines are **incomplete**.
|
||||
|
||||
Incomplete lines don't have any incorrect characters - instead, they're missing some closing characters at the end of the line. To repair the navigation subsystem, you just need to figure out **the sequence of closing characters** that complete all open chunks in the line.
|
||||
|
||||
You can only use closing characters (`)`, `]`, `}`, or `>`), and you must add them in the correct order so that only legal pairs are formed and all chunks end up closed.
|
||||
|
||||
In the example above, there are five incomplete lines:
|
||||
|
||||
- `[({(<(())[]>[[{[]{<()<>>` - Complete by adding `}}]])})]`.
|
||||
- `[(()[<>])]({[<{<<[]>>(` - Complete by adding `)}>]})`.
|
||||
- `(((({<>}<{<{<>}{[]{[]{}` - Complete by adding `}}>}>))))`.
|
||||
- `{<[[]]>}<{[{[{[]{()[[[]` - Complete by adding `]]}}]}]}>`.
|
||||
- `<{([{{}}[<[[[<>{}]]]>[]]` - Complete by adding `])}>`.
|
||||
|
||||
Did you know that autocomplete tools **also** have contests? It's true! The score is determined by considering the completion string character-by-character. Start with a total score of `0`. Then, for each character, multiply the total score by 5 and then increase the total score by the point value given for the character in the following table:
|
||||
|
||||
- `)`: `1` point.
|
||||
- `]`: `2` points.
|
||||
- `}`: `3` points.
|
||||
- `>`: `4` points.
|
||||
|
||||
So, the last completion string above - `])}>` - would be scored as follows:
|
||||
|
||||
- Start with a total score of `0`.
|
||||
- Multiply the total score by 5 to get `0`, then add the value of `]` (2) to get a new total score of `2`.
|
||||
- Multiply the total score by 5 to get `10`, then add the value of `)` (1) to get a new total score of `11`.
|
||||
- Multiply the total score by 5 to get `55`, then add the value of `}` (3) to get a new total score of `58`.
|
||||
- Multiply the total score by 5 to get `290`, then add the value of `>` (4) to get a new total score of `294`.
|
||||
|
||||
The five lines' completion strings have total scores as follows:
|
||||
|
||||
- `}}]])})]` - `288957` total points.
|
||||
- `)}>]})` - `5566` total points.
|
||||
- `}}>}>))))` - `1480781` total points.
|
||||
- `]]}}]}]}>` - `995444` total points.
|
||||
- `])}>` - `294` total points.
|
||||
|
||||
Autocomplete tools are an odd bunch: the winner is found by **sorting** all of the scores and then taking the **middle** score. (There will always be an odd number of scores to consider.) In this example, the middle score is **`288957`** because there are the same number of scores smaller and larger than it.
|
||||
|
||||
Find the completion string for each incomplete line, score the completion strings, and sort the scores. **What is the middle score?**
