Bad news: your worst enemies are at the gate. Your fledgling kingdom guards the world’s only herd of tiny dino creatures. To you, they’re sacred. To everyone else, they’re food. The three closest nation-states have teamed up to smash open your walls and devour the herd. Can you build fortifications for your kingdom before the siege weapons arrive? Henri Picciotto shows how.

@Nuoska 2 года назад

Here's how I solved it: The greatest common divisor of 6 and 9 is 3, and the largest safe wall of size 3n is 3. This means that every wall of size 3n that is larger than 3 can be destroyed. Therefore, a bigger wall would have to be 3n+1 or 3n+2. The siege weapons can only reach 3n+2 numbers by using the 20 once or 3n+1 times, and since they can reach every multiple of 3 larger than 3, every 3n+2 wall larger than 20+3 can be destroyed. Similarly they can only reach 3n+1 numbers by using the 20 twice or 3n+2 times, so every 3n+1 wall larger than 20+20+3 can be destroyed. 43 is safe and no larger safe walls can exist, so 43 must be the answer.

For the first time watching one of these riddle videos I actually decided to try and solve it and got the answer by 1. Listing every number up to 60 2. Removing every multiple of 3 except 3 because they can be made with combinations of 6's and 9's 3. Repeating step 2 but starting from 20 then removing 26, 29, 32, 35 etc. 4. Notice a pattern and realise that I don't need to go beyond 60 5. Highest number left is 43! It's not the most elegant solution but that doesn't mean I can't be proud of myself.

Alternatively, point the wall fabricator at your enemies and tell it to produce a 100 000 m long wall. Due to the machine producing any size of wall at equal speed, this huge wall will be shot out of the machine at outstanding speed, crushing your opponents. Unless it, uh, requires raw materials or something.

If the wall fabricator's input unit is in inches, then the required amount of inches to be inputted for the fabricator to be fabricating so many inches of wall at once that it would be travelling at 99% the speed of light, then you would need to input about 1.43 times 10^10 inches

@newpgaston6891 2 года назад

Found it even faster, using a different method! Any multiple of 3 can be divided by a combination of 6s and 9s, except 3. If a number isn't divisible by 3, then it WILL become divisible by 3 if you remove 20 or 40 from it. (because it changes the rest, and changing it either once or twice always work). This means that any number higher than 40 is either: 1) Divisible by 3 2) Will be divisible by 3 if you remove 20 3) Will be divisible by 3 if you remove 20 twice (so, 40) And if the number is divisible by 3 and it's above 3, it's no good. (the added 20 don't matter because one of the wallbreakers can take the 20s down). So if you remove 20 or 40 from the number, it can't ever give you a number divisible by 3, that is above 3. But as you're looking for the highest possible solution, then it has to be the solution where the number you get from removing 20 or 40 gives you EXACTLY 3; Between 23 and 43, you obviously pick 43, and that's the highest possible solution! Anything above that will either divide by 3, or divide by 3 if you remove 20 or 40 from it (and if it divides by 3, it means you can get it with the 6s and 9s, no matter what it is - as long as it's not 3, but we already picked the solution that gives you 3, i.e. 43).

@aarongrooves 2 года назад

43? Okay, time to check my answer... Yay! I got it :) I realized that 3 is the greatest common factor between 6 and 9, so all multiples of 3 will be eliminated from 6 onward. If you add 20 to this, then you end up at 26, which eliminates all multiples of 3 minus 1 from 26 onward. Once you get to 46, then you eliminate all multiples of 3 plus 1. At this point, you can create any number. The highest number that wasn't eliminated is multiples of 3 plus 1, but less than 46. Which is 43. Fun math problem!

@tonito5588 2 года назад

Got it with a different method after a few takeaways. - Realized you can get all multiples of 3 (except for 3 itself) with 6 and 9 alone. - If you can prove that you can find all lowest multiples of three such that 3A=20B+x for every integer x from [1,20], you could basically make any number greater than the greatest of those multiples (ex. for x=4 you have 3*8=20*1+4). This works since if we have a representation like this for each number from 1-20, we can just add multiples of 20 to one of these to get any other natural number greater than these representations we find. Note that A and B must be natural numbers. - It turns out that you can find those lowest multiples of three in the first 20 multiples. The greatest of these low multiples is 63 (for x=3 we have 3*21=20*3+3). - Since 63 is the lowest number we can find for a representation of x=3, there must be no representation for 43 (since it is 20*2+3) or 23 (since it is 20*1+3). Since 63 is the greatest among these "low" multiple representations, 43 must be the greatest number without a representation made up from 6,9,20. How did you all do it?

@Sargas-wielder 2 года назад

I had a similar sort of elimination method: With 6 and 9 you can make any multiple of 3 besides 3 itself, and only multiples of 3 with those 2 numbers 20 is 1 less than a multiple of three so, above 20, you can add 6s and 9s to get 1 less than any multiple of 3 besides 23 40 is 2 less than a multiple of 3, so similar to the last step, beyond 40, you can add 6s and 9s to get 2 less than any multiple of 3 besides 43, effectively eliminating all numbers past 43 since you've already eliminated multiples of 3, one less than multiples of 3, and 2 less than multiples of 3

My solve was a little different. The first thing I realized was that with 6 and 9, you could combine them to make any multiple of 3 above 6 (6+6=12, 6+9=15, etc.). Then using the 20, you would be able to offset it down one number, so multiples of 3, minus 1 (20+9= 30-1). So offsetting it a second time, with 40, would remove every potential number. So the highest available number would be a number less than 46, that is offset from a multiple of 3 by -2, 45 - 2 = 43. Not the solution they hit on, but I'm proud of it.

If the dinos are sought after as a food source, is there something special about the food source or are the invading forces starving? The latter seems more likely and you could simply create rows of walls and wait until they go hungry. The walls would also have to either be fabricated "into place" from the side of the machine, or physically moved into place. If it's the latter, the invaders could just move the walls. But all of that ignores that the camped forces could attack the engineers in the video's scenario or mine through scout parties in the night. (And that the machine is apparently able to fabricate entire walls in equivalent degrees of time regardless of the size)

I used the divisible-by-three insight some other commentors mentioned, knowing that only 20's could change the divisibility by three. Knowing that it would take up to two 20's to make the number easily divisible by three, I started with 39, the biggest number you couldn't fit two 20's into, and counted backwards from there until I hit a number that couldn't be made any other way. Thus, I got the answer 37. ...apparently I overlooked the fact that the number 3 itself couldn't be made, only greater multiples thereof.

@erickpoorbaugh6728 2 года назад

I used a different method. 6 and 9 are both multiples of 3, so the 20s have to be used to make up for any remainder when divided by 3, so if you let them use three or more 20s, they can replace three of the 20s with 6s and 9s to get more options, but if you keep it to no more than two 20s, they don't have this option. Now if you divide 6 and 9 by 3, you get 2 and 3, which together can cover any number larger than 1, since for even numbers you just use 2s, and for odd numbers you use 2s to get to the even number below your target and then replace the the last 2 with a 3. Thus, the only multiple of 3 that 6 and 9 can't cover is 3 (1x3). Add the two 20s (that are the most 20s you can use without letting them start from a lower number of 20s) and you get 43.

What I'm not clear on is the underlying principle for solving for prime numbers using the chart. While eliminating the factors of 2,3,5, and 7 are good through 120, you'd need to also run that elimination for the higher primes to eliminate numbers like 187, which is 11 * 17. Unless it's all diagonals all the way down, which would be harder as you have to start skipping lines.

@Lance0 2 года назад

The nice thing about 6 columns is that all primes except for 2 and 3 are actually of the form 6n+1 or 6n-1. This does in fact make it diagonals all the way down. And I mean ALL the way down. Every single one of them. Yes the slopes would be much steeper but they're still straight lines.

@伊紹菲 2 года назад

I did this in a fairly roundabout way- first you figure out the smallest combos of 6s and 9s to get to various numbers in the 1s spot. The largest number combo of 6s and 9s is 33 to get a 3 in the 1’s spot, so it would be advantageous then, to have a 3 as the last number, since it’d take up more of the entire number to get it to a multiple of 10, would then be divided by 20s, or an additional 30 if it’s an odd number of 10s. With all that in mind, only 43 would work, as 53 gives you a 20, 63 a 30, and literally everything else can be solved by all 20s or a bunch of 20s + 30. So it was indeed 43.

@ie8118 2 года назад

My Feedback: So I did this by listing numbers up and basically through manual testing them all to see if they could be sieged. The problem is I didn't clearly get that you were going to make 1 wall out of segments of the same length and the point was to use the longest segment length possible in order to minimize the wall making time/number of segment used. I thought that you could only do 1 print total and that was going to be the whole wall, because it talked about the machine taking the same amount of time to print any length. I was just under the impression you only had time to do 1 print before the enemies got here, totally forgot about what it said at the start about how it can make segments of a specific whole number length you set. I think the main thing that would help is that instead of the question at 2:00 being "What wall length will save your kingdom?" say "what wall segment length" instead. I have a suspicion this is the main thing that confused me. Also, at 1:54 when it shows the segment, it could show it as a part of many other segments of similar size to emphasize you want to figure out the segment length not the whole wall length. (I know the voice says segment but I must have missed that). The clock being shown to take a full 12 hour cycle to print 1 segment also might have been misleading, not by itself but in combination with the other things like the question wording. The sentence "Adjacent wall segments reinforce each other if struck simultaneously" is just confusing. It basically just means "A siege weapon cannot take down multiple segments at once- only 1 segment at a time." and I think this would be much clearer.

@ronaldiplodicus 2 года назад

It does say that the final wall will be 1km wide

@ie8118 2 года назад

@@ronaldiplodicus Yeah if it said it would be exactly 1km wide then I'd know the answer was the segment size. But since it said at the countdown that it doesn't have to be exactly 1km because you can fill the ends with rocks, I was still able to keep the wrong impression that the answer is the total wall length

@gamixhyperdrive8425 Год назад

While I didn't get the solution (and actually tried trial and error lol), the solution shown is strange. Yes, 43 cannot be made out of 6s, 9s and 20s. I fully agree there. What I don't agree with is what is shown and presented during the video. Here's the thing... It shows that Redheadonia's weapon is 20m wide. At 1:30 however is what is the confusing part. It shows 4x7 walls that in total are 28. This wall is considered as 28 now and cannot be taken down.... but if I add more walls with the length 7 this way (since that 28 is made out of 7s as SHOWN in the video) it will reach 63 which can be breached by 9m. So while 43m walls alone can hold out... a 86m wall will crumble. Now, I hear the explanations already "It overlaps so it cannot break!", etc., etc. Then the video should've shown it properly. To me, the 28 made out of 4x7 was very misleading because what keeps me away from also just attacking it with 2 6s and 1 9? That's 21 which would break that 3x7 segment. That's just how I see it though. I also thought that because of this you could make different lengths at one point since reprogramming it seemed fairly easy (but rereading the rules clearly meant that I can print only one wall segment length). In the end, visuals and rules contradicted each other. Who knows if it would've been better without them or correct visuals...

Enjoy your impregnable fortress while the long siege wears down the defenders and as food supplies dwindle, the morale of the soldiers dropped to rock bottom until eventually you are left with the ultimate choice you need to make to survive. At that point, everyone else has made their own choices on the matter. Chaos reigns as the people who chose to abandon their faith over their hunger stormed the creatures' sanctuary and the starved defenders need to point their weapons to their fellow countrymen, resulting in a lot of losses. But wait, look at all these fresh bodies! Surely they were provided to you by the gods themselves to let you survive just a bit longer? You command the troops to gather and not to waste a single cadaver, anyone who refuses to eat will be put to the sword to become part of the meal! We are following a divine calling after all. Our lives will serve the gods until the end! Thus went the day, two days, three days, a week, two weeks, three weeks. The chaos has toned down as anyone who would openly revolt has died and become food. The masses is back to starving. Some rumors on the street is the remaining pockets of resistance will try to open the gates and let the enemies in. You began to suspect eveyone but your closest friends. The paranoia led to more killings, as anyone suspected of betrayal will be immediately punished. Until three months later. You have lost 70% of the original population of your country. At one night, while the constant guilt and paranoia kept you awake, your "friends" visited your room. They have had enough. All of them began stabbing you and while you fall to the floor in a pool of blood, you see them slitting their own necks. Ah, the country you've fought so hard to protect. Will the gods at least be proud of what you've done?

@redfluxbluedawn414 2 года назад

I seem to be missing something... The width to be defended is 1000, which isn't divisable by 43, so that leaves a gap of 11 through which the enemies can get in? Wouldn't it be simpler to produce 997 + 3 instead of 23 * 43? Or if you want to stick to 43, produce 1 extra piece of 11 to close the gap?
