It's that time of the year*, and Santa is delivering presents to all the good children of the world.
*Almost, since the fortnightly challenge is a tad late :)
Informed by his elves that his sacks are space inefficient, Santa has decided to trial groundbreaking orthogonal sacks that are solid and compact. Leaving the packing up to the elves, as always, Santa set off on Christmas Eve carrying these solid sacks, which admittedly helped reduce the space required in his sleigh from an extremely absurd and impossible amount of space down to a somewhat absurd and impossible amount of space.
However, upon arriving at his first house, Santa realized that it was actually quite difficult to remove the presents from these sacks. The elves had packed the presents in strange, strange ways, and now it was up to him to get them back out of the sacks.
Shown below are cross sections of some of Santa's sacks (brown is the sack, unmovable, and variously shaped presents are contained within each sack). Can you slide all of the presents out of each sack?
(Clarification on rules: The brown sack portions are stiff and immovable. The presents can move freely within empty space, but at no point can overlap with another present. Santa doesn't delivered squashed presents!)
Note from Santa: I was under the impression that we were using these newfangled sacks for space efficiency, but the elves have gone ahead and packed some with empty space inside! I can never trust those little fiends.
Note from Santa: This sack is of low quality and has some extra holes, as you can see. I'm mildly suspicious that the elves made those holes themselves... I don't think the presents are removable without using them.
Oh well, at least this sack is fully packed.
Note from Santa: When I was unpacking this sack, I had just about HAD it with the elves! I managed to take everything out apart from the red present, which I'm sure you can see is impossible to take out. I complained about this to the elves, and they soaked the sack in fabric softener to get the red present out - and it was a fresh new red coat for me!
Despite all their intrusive, inconvenient, inane and immature pranks, the elves are always good at heart... despite putting my present delivery off schedule by 3 days.
Note from TheGreatEscaper: Merry Belated Christmas and a Happy Be-Earlied New Year!!!
