## \--- Day 5: Hydrothermal Venture ---
|
||||||
|
|
||||||
|
You come across a field of [hydrothermal
|
||||||
|
vents](https://en.wikipedia.org/wiki/Hydrothermal_vent) on the ocean floor!
|
||||||
|
These vents constantly produce large, opaque clouds, so it would be best to
|
||||||
|
avoid them if possible.
|
||||||
|
|
||||||
|
They tend to form in _lines_ ; the submarine helpfully produces a list of
|
||||||
|
nearby lines of vents (your puzzle input) for you to review. For example:
|
||||||
|
|
||||||
|
[code]
|
||||||
|
|
||||||
|
0,9 -> 5,9
|
||||||
|
8,0 -> 0,8
|
||||||
|
9,4 -> 3,4
|
||||||
|
2,2 -> 2,1
|
||||||
|
7,0 -> 7,4
|
||||||
|
6,4 -> 2,0
|
||||||
|
0,9 -> 2,9
|
||||||
|
3,4 -> 1,4
|
||||||
|
0,0 -> 8,8
|
||||||
|
5,5 -> 8,2
|
||||||
|
|
||||||
|
[/code]
|
||||||
|
|
||||||
|
Each line of vents is given as a line segment in the format `x1,y1 -> x2,y2`
|
||||||
|
where `x1`,`y1` are the coordinates of one end the line segment and `x2`,`y2`
|
||||||
|
are the coordinates of the other end. These line segments include the points
|
||||||
|
at both ends. In other words:
|
||||||
|
|
||||||
|
* An entry like `1,1 -> 1,3` covers points `1,1`, `1,2`, and `1,3`.
|
||||||
|
* An entry like `9,7 -> 7,7` covers points `9,7`, `8,7`, and `7,7`.
|
||||||
|
|
||||||
|
For now, _only consider horizontal and vertical lines_ : lines where either
|
||||||
|
`x1 = x2` or `y1 = y2`.
|
||||||
|
|
||||||
|
So, the horizontal and vertical lines from the above list would produce the
|
||||||
|
following diagram:
|
||||||
|
|
||||||
|
[code]
|
||||||
|
|
||||||
|
.......1..
|
||||||
|
..1....1..
|
||||||
|
..1....1..
|
||||||

||||||

||||||
|
..........
|
||||||
|
..........
|
||||||
|
222111....
|
||||||
|
|
||||||
|
[/code]
|
||||||
|
|
||||||
|
In this diagram, the top left corner is `0,0` and the bottom right corner is
|
||||||
|
`9,9`. Each position is shown as _the number of lines which cover that point_
|
||||||
|
or `.` if no line covers that point. The top-left pair of `1`s, for example,
|
||||||
|
comes from `2,2 -> 2,1`; the very bottom row is formed by the overlapping
|
||||||
|
lines `0,9 -> 5,9` and `0,9 -> 2,9`.
|
||||||
|
|
||||||
|
To avoid the most dangerous areas, you need to determine _the number of points
|
||||||
|
where at least two lines overlap_. In the above example, this is anywhere in
|
||||||
|
the diagram with a `2` or larger - a total of `_5_` points.
|
||||||
|
|
||||||
|
Consider only horizontal and vertical lines. _At how many points do at least
|
||||||
|
two lines overlap?_
