# No Time For Directions!
**Hermes** is the Greek god, and amongst others, he is the god of travel, trade, and athletes.
Hermes has placed his hope in you.
You're dropped to a random location near Mount Cyllene in Arcadia, widely considered the birthplace
of Hermes. After years of training, **You** are now set out on a quest. You must steal a key from
**Hecate**, hidden near Mount Cyllene.
Unfortunately, "near", is as close as you know where you are. The instructions on the parchment
Hermes gave begin from here, however, he never had the time to tell you how to follow them, or where
they lead to.
The document has different markings that appear to tell you which direction to travel in. They
indicate a direction, (`N`, `S`, `E` or `W`), and the number of steps you must take to find the
hiding location.
The problem is, that there's over a 100 different directions, and there's no time following these
directions one by one. It will take far too long! You take a moment and work out the final
destination, so you can get more quickly. Given that you can only walk in the cardinal directions,
what is the shortest path to the destination?
### Example
- Given the following input
```
N5
E2
S9
W3
```
Instructs you to to travel `5` steps North, `2` steps East, `9` steps South,
and `3` steps West. Simplifying it, means `4` steps South, and `1` step West,
or `5` steps away.
- Given the following input
```
N6
E5
N5
W3
N4
S9
E4
S1
W6
E3
```
Leaves you `5` steps North, and `3` steps East, or `8` steps away.
Each line will have **at least 2** characters of input, the first being the direction, and
the second being the number of steps. The number of steps on each line will
always be between 1 and 9, inclusive, steps.
**How many steps away** is the key?
{{ if eq .Part 2 }}
**Congratulations! You got Part 1 correct. Your answer was `{{ .Answer1 }}`.**
## Part 2
After some more inspection of the instructions, you decipher the final clue. The final location of
the steps lead you to a different location. However, the first location you visit **twice** is the
location where the key is hidden.
### Example
Given the following input:
```
S7
W9
E4
N4
S3
E5
S1
```
The first location visit twice is `7` blocks away South.
With these new instructions, to find the key, **how many steps away is the first location you visit
twice?**
