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 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?

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.
|
