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?

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.

|
|
|
|
puzzle.
