\--- Day 3: Squares With Three Sides ---
----------

Now that you can think clearly, you move deeper into the labyrinth of hallways and office furniture that makes up this part of Easter Bunny HQ. This must be a graphic design department; the walls are covered in specifications for triangles.

Or are they?

The design document gives the side lengths of each triangle it describes, but... `5 10 25`? Some of these aren't triangles. You can't help but mark the impossible ones.

In a valid triangle, the sum of any two sides must be larger than the remaining side. For example, the "triangle" given above is impossible, because `5 + 10` is not larger than `25`.

In your puzzle input, *how many* of the listed triangles are *possible*?

Your puzzle answer was `1050`.

\--- Part Two ---
----------

Now that you've helpfully marked up their design documents, it occurs to you that triangles are specified in groups of three *vertically*. Each set of three numbers in a column specifies a triangle. Rows are unrelated.

For example, given the following specification, numbers with the same hundreds digit would be part of the same triangle:

```
101 301 501
102 302 502
103 303 503
201 401 601
202 402 602
203 403 603

```

In your puzzle input, and instead reading by columns, *how many* of the listed triangles are *possible*?

Your puzzle answer was `1921`.

Both parts of this puzzle are complete! They provide two gold stars: \*\*

At this point, all that is left is for you to [admire your Advent calendar](/2016).
