34 049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	1 --- Day 13: Packet Scanners ---
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	2
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	3 You need to cross a vast firewall. The firewall consists of several
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	4 layers, each with a security scanner that moves back and forth across
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	5 the layer. To succeed, you must not be detected by a scanner.
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	6
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	7 By studying the firewall briefly, you are able to record (in your
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	8 puzzle input) the depth of each layer and the range of the scanning
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	9 area for the scanner within it, written as depth: range. Each layer
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	10 has a thickness of exactly 1. A layer at depth 0 begins immediately
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	11 inside the firewall; a layer at depth 1 would start immediately after
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	12 that.
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	13
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	14 For example, suppose you've recorded the following:
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	15
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	16 0: 3
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	17 1: 2
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	18 4: 4
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	19 6: 4
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	20
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	21 This means that there is a layer immediately inside the firewall (with
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	22 range 3), a second layer immediately after that (with range 2), a
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	23 third layer which begins at depth 4 (with range 4), and a fourth layer
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	24 which begins at depth 6 (also with range 4). Visually, it might look
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	25 like this:
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	26

049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	33 Within each layer, a security scanner moves back and forth within its
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	34 range. Each security scanner starts at the top and moves down until it
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	35 reaches the bottom, then moves up until it reaches the top, and
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	36 repeats. A security scanner takes one picosecond to move one step.

049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	68 Your plan is to hitch a ride on a packet about to move through the
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	69 firewall. The packet will travel along the top of each layer, and it
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	70 moves at one layer per picosecond. Each picosecond, the packet moves
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	71 one layer forward (its first move takes it into layer 0), and then the
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	72 scanners move one step. If there is a scanner at the top of the layer
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	73 as your packet enters it, you are caught. (If a scanner moves into the
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	74 top of its layer while you are there, you are not caught: it doesn't
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	75 have time to notice you before you leave.) If you were to do this in

049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	77 parentheses, your passage through the firewall would look like this:

049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	183 In this situation, you are caught in layers 0 and 6, because your
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	184 packet entered the layer when its scanner was at the top when you
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	185 entered it. You are not caught in layer 1, since the scanner moved
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	186 into the top of the layer once you were already there.
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	187
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	188 The severity of getting caught on a layer is equal to its depth
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	189 multiplied by its range. (Ignore layers in which you do not get
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	190 caught.) The severity of the whole trip is the sum of these values. In
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	191 the example above, the trip severity is 03 + 64 = 24.

049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	193 Given the details of the firewall you've recorded, if you leave

049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	200 Now, you need to pass through the firewall without being caught -
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	201 easier said than done.
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	202
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	203 You can't control the speed of the packet, but you can delay it any
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	204 number of picoseconds. For each picosecond you delay the packet before
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	205 beginning your trip, all security scanners move one step. You're not
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	206 in the firewall during this time; you don't enter layer 0 until you
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	207 stop delaying the packet.

049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	209 In the example above, if you delay 10 picoseconds (picoseconds 0 - 9),
049fb8e56025 Add problem statements and inputs Jordi Gutiérrez Hermoso <jordigh@octave.org> parents: diff changeset	210 you won't get caught:
