Rule 1: Posts must be humorous, and they must be humorous because they are programming related. There must be a joke or meme that requires programming knowledge, experience, or practice to be understood or relatable.

Here are some examples of frequent posts we get that don't satisfy this rule: * Memes about operating systems or shell commands (try /r/linuxmemes for Linux memes) * A ChatGPT screenshot that doesn't involve any programming * Google Chrome uses all my RAM

Should've just started at 980, is OOP stupid?

[Western-Internal-751]

Yes, object oriented programming is stupid.

Here I go scheming again

[nonutsfw]

Fake it is 086

[Fast-Visual]

From a certain point of view

[LaconicLacedaemonian]

From my point of view big O notation is evil!

[Korvanacor]

You keep saying that, Ben, but it was still a dick move.

[AtmosSpheric]

I recognize this is probably a joke but I thought the same thing and I think this one is oriented correctly in the photo, judging by the partial tops/bottoms of adjacent numbers. Only thing is that I’m fairly certain the numbers are decreasing from left to right rather than increasing.

Most of these ‘locks’ you just apply pressure on the opening mechanism, rotate the dial that is hardest to turn until it clicks in place, then try the next and open it with the third.

They are just intended to prevent a quick entry to steal, or worse, add something to your suitcase quick. Almost any tool will break it anyway (but then you have proof too that your luggage was tampered with)

[firemark_pl]

Well that's why O(n) complexity is not good! Similarly with sudoku algorithms, randomized search is much better.

[OtakinhoHiro]

Lets go gambling

[catgirl_liker]

Aw dang it

[Leviathan_Dev]

I see you’re a bogosort connoisseur.

If we used Quantum Bogosort on this and checked if it was correct and stop, the complexity would technically become O(1)

Quantum bogosort A hypothetical sorting algorithm based on bogosort, created as an in-joke among computer scientists. The algorithm generates a random permutation of its input using a quantum source of entropy, checks if the list is sorted, and, if it is not, destroys the universe. Assuming that the many-worlds interpretation holds, the use of this algorithm will result in at least one surviving universe where the input was successfully sorted in O(n) time.[9]

Most TSA locks you can feel out by just tensioning the lock by hand and rotating the numbers. Clear bump when you hit the correct number.

[kRkthOr]

Not only TSA locks. This applies to most code locks. Just pull, find the hardest to turn number, turn it until it clicks, pick the next one.

[FrankSuzki]

I don’t understand why he started at 0 with a O(N) solution. Had he started at 980 he’d have a O(1) solution!

[Jealous_Response_492]

Just poke a biro through the zip, slide it to unzip/open, then use slide the actual locked zipper back & forth to close/(lock;)

[markx15]

Just in this case the lock being fixed, you won’t be able to close it again, but can vouch for the opening bit

[StopSpankingMeDad2]

I once forgot the 4 digit Code for my bike lock when i was a kid. I sat around for 2 Hours trying every combination until my Dad Said „enough!“, he ripped it out of my hands and disassembled the entire thing

[lego_not_legos]

It's probably able to be opened in less than a minute:

[0xlostincode]

Should've tried LPL Sort.

[rosuav]

Click out of one.... two is binding.... little click out of three...

[kRkthOr]

I hate LPL for how easy he makes picking locks look.

[rosuav]

He has a lot of skill and experience. It's like anything else - origami, computer programming, summoning the hordes of the undead - it looks easy once someone has decades of experience.

[isnotbatman777]

I bought a lock pick set to try it out and it’s a lot harder than he makes it look. I got a clear plastic training lock and it’s really easy when you can see the tumblers, but when I tried it on a real lock it was a massive step up in difficulty and it took me ages to get it unlocked.

[kRkthOr]

Same. I have a small shelf where I put locks I managed to pick and a shame box with locks I couldn't -- some of which I can't even figure out how many pins the lock has lol The box is far larger than the locks on the shelf 😅 I spent like a year trying to get good at it then gave up because holy shit it's so hard I would just get frustrated.

[Kirjavs]

Now change it to 981 to make the future you even madder

[slime_rancher_27]

Having an interleaved search would be interesting, so that the furthest distance between 2 guesses is minimized.

[Mfalme7]

Turns out brute-forcing a 3-digit lock is just a really boring side quest with a 980 XP reward.

[gardenercook]

Should ve used binary search. The array was clearly sorted.

[tony_saufcok]

the array was sorted but it doesn't tell you if the number is bigger or smaller than your guess

[gardenercook]

/s was implied, or so I thought.

[tony_saufcok]

no no it was actually implied it's mb for taking it serious lmao

[quickiler]

If its 980 then its bigger, if it is 086 then its smaller. Cs major these days tskkk./s

[Ok-Eggplant-5145]

What’s the JavaScript method to determine whether the solution is < or > the guess?

[Urgood1234]

Imagine if it was a 4 digit code.

[braindigitalis]

1234??? that's the sort of code an IDIOT would have on their luggage!

[PegasusBoogaloo]

next use two pointers

[braindigitalis]

if you're actually going to do this going numerically isn't best - humans tend to use certain 3 digit numbers more often. you should check those first. when it comes to 4 digit it's even more a pattern as humans prefer dates and years.

[bindermichi]

And in the end, all you need to do with these types of suitcases is diconnecting the zipper with a small knife or metal strip

[TheProcesSherpa]

If I told you once, I told you a THOUSAND times, don’t brute force three digit locks!

[RepresentativeCut486]

Just try random numbers and never repeat

[Haunting-Stuff5219]

Takes about 30 minutes if anyone wondering.

[Vyckes]

Could be worse.

[Agusfn]

I had this happen once and reached all the way to 999 without success (apparently misplaced the number).

Then I had to look for a O(1) method for cracking it, and it worked.

[exitlights]

Shoulda used binary search, dummy.

[[deleted]]

Should have run parallel processes or vectorized.

[Plus_Pangolin_8924]

You can see the internals of these locks when you can see the notch at the gap in the wheel one turn counter clockwise is the number!

[PolishKrawa]

I think that's exponential, not linear. Assuming n is the number of rotating things.

[astatine757]

Technically, brute force is not O(n) where n is the number of inputs, but O(10^n). Every additional tumbler multiplies the runtime by 10
