\--- Day 15: Science for Hungry People ---
----------

Today, you set out on the task of perfecting your milk-dunking cookie recipe. All you have to do is find the right balance of ingredients.

Your recipe leaves room for exactly `100` teaspoons of ingredients. You make a list of the *remaining ingredients you could use to finish the recipe* (your puzzle input) and their *properties per teaspoon*:

* `capacity` (how well it helps the cookie absorb milk)
* `durability` (how well it keeps the cookie intact when full of milk)
* `flavor` (how tasty it makes the cookie)
* `texture` (how it improves the feel of the cookie)
* `calories` (how many calories it adds to the cookie)

You can only measure ingredients in whole-teaspoon amounts accurately, and you have to be accurate so you can reproduce your results in the future. The *total score* of a cookie can be found by adding up each of the properties (negative totals become `0`) and then multiplying together everything except calories.

For instance, suppose you have these two ingredients:

```
Butterscotch: capacity -1, durability -2, flavor 6, texture 3, calories 8
Cinnamon: capacity 2, durability 3, flavor -2, texture -1, calories 3

```

Then, choosing to use `44` teaspoons of butterscotch and `56` teaspoons of cinnamon (because the amounts of each ingredient must add up to `100`) would result in a cookie with the following properties:

* A `capacity` of `44*-1 + 56*2 = 68`
* A `durability` of `44*-2 + 56*3 = 80`
* A `flavor` of `44*6 + 56*-2 = 152`
* A `texture` of `44*3 + 56*-1 = 76`

Multiplying these together (`68 * 80 * 152 * 76`, ignoring `calories` for now) results in a total score of `62842880`, which happens to be the best score possible given these ingredients. If any properties had produced a negative total, it would have instead become zero, causing the whole score to multiply to zero.

Given the ingredients in your kitchen and their properties, what is the *total score* of the highest-scoring cookie you can make?

Your puzzle answer was `222870`.

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

Your cookie recipe becomes wildly popular! Someone asks if you can make another recipe that has exactly `500` calories per cookie (so they can use it as a meal replacement). Keep the rest of your award-winning process the same (100 teaspoons, same ingredients, same scoring system).

For example, given the ingredients above, if you had instead selected `40` teaspoons of butterscotch and `60` teaspoons of cinnamon (which still adds to `100`), the total calorie count would be `40*8 + 60*3 = 500`. The total score would go down, though: only `57600000`, the best you can do in such trying circumstances.

Given the ingredients in your kitchen and their properties, what is the *total score* of the highest-scoring cookie you can make with a calorie total of `500`?

Your puzzle answer was `117936`.
