----------

Santa's Accounting-Elves need help balancing the books after a recent order. Unfortunately, their accounting software uses a peculiar storage format. That's where you come in.
|
|
|
|
They have a [JSON](http://json.org/) document which contains a variety of things: arrays (`[1,2,3]`), objects (`{"a":1, "b":2}`), numbers, and strings. Your first job is to simply find all of the *numbers* throughout the document and add them together.
|
|
|
|
For example:
|
|
|
|
* `[1,2,3]` and `{"a":2,"b":4}` both have a sum of `6`.
|
|
* `[[[3]]]` and `{"a":{"b":4},"c":-1}` both have a sum of `3`.
|
|
* `{"a":[-1,1]}` and `[-1,{"a":1}]` both have a sum of `0`.
|
|
* `[]` and `{}` both have a sum of `0`.
|
|
|
|
You will not encounter any strings containing numbers.
|
|
|
|
What is the *sum of all numbers* in the document?
|
|
|
|
Your puzzle answer was `119433`.

|
\--- Part Two ---
|
|
----------
|
|
|
|
Uh oh - the Accounting-Elves have realized that they double-counted everything *red*.
|
|
|
|
Ignore any object (and all of its children) which has any property with the value `"red"`. Do this only for objects (`{...}`), not arrays (`[...]`).
|
|
|
|
* `[1,2,3]` still has a sum of `6`.
|
|
* `[1,{"c":"red","b":2},3]` now has a sum of `4`, because the middle object is ignored.
|
|
* `{"d":"red","e":[1,2,3,4],"f":5}` now has a sum of `0`, because the entire structure is ignored.
|
|
* `[1,"red",5]` has a sum of `6`, because `"red"` in an array has no effect.
|
|
|
|
Your puzzle answer was `68466`.
