--- Day 17: No Such Thing as Too Much ---
|
||
|
||
The elves bought too much eggnog again - 150 liters this time. To fit it all into your
|
||
refrigerator, you'll need to move it into smaller containers. You take an inventory of the
|
||
capacities of the available containers.
|
||
|
||
For example, suppose you have containers of size 20, 15, 10, 5, and 5 liters. If you need to
|
||
store 25 liters, there are four ways to do it:
|
||
|
||
• 15 and 10
|
||
• 20 and 5 (the first 5)
|
||
• 20 and 5 (the second 5)
|
||
• 15, 5, and 5
|
||
|
||
Filling all containers entirely, how many different combinations of containers can exactly fit
|
||
all 150 liters of eggnog?
|
||
|
||
Your puzzle answer was 1304.
|
||
|
||
--- Part Two ---
|
||
|
||
While playing with all the containers in the kitchen, another load of eggnog arrives! The
|
||
shipping and receiving department is requesting as many containers as you can spare.
|
||
|
||
Find the minimum number of containers that can exactly fit all 150 liters of eggnog. How many
|
||
different ways can you fill that number of containers and still hold exactly 150 litres?
|
||
|
||
In the example above, the minimum number of containers was two. There were three ways to use
|
||
that many containers, and so the answer there would be 3.
|
||
|
||
Your puzzle answer was 18.
|
||
|
||
Both parts of this puzzle are complete! They provide two gold stars: **
|
||
|
||
At this point, you should return to your advent calendar and try another puzzle.
