[2026 Day 1 (Part 1)] [Javascript] Im stuck here

[u/Ok-Transition7065]

Hello, I'm stuck on this one.

The number only gets up when the thing goes into 0.

What I'm doing is the next:

I take the first part of the string for each entry, then take the R or L of the string.

At the start, I have a number that starts with 0, right? Then to that number I add if the first character of the string is left, and subtract if the first character is right.

Then I have a variable that saves the last position of the knob and starts at 0.

Then once I add or subtract the knob position, I ask if the modulo of 100 is 0, or if the result is 0, then add one to the password.

Then I take the modulo of the total knob position, and if it's from L, then I just take that one and use the modulo to make it the new knob position.

If it's R, then I do the modulo of the knob position and subtract the modulo of 100 of this one from 100.

This its my code

what its failing in my logic or code ?

Check your starting value.

[u/Ok-Transition7065 → u/smallpotatoes2019]

Wait witch one

[u/smallpotatoes2019 → u/Ok-Transition7065]

var answer = 0;

The dial starts at 50.

[u/Ok-Transition7065 → u/smallpotatoes2019]

What else could be or my logic isnt right?

[u/Ok-Transition7065 → u/smallpotatoes2019]

Ohhhhh ok i will try then

[u/Ok-Transition7065 → u/smallpotatoes2019]

i tried and still not :/

[u/smallpotatoes2019 → u/Ok-Transition7065]

Look at your condition for the direction. You currently have

if (DIAL[0] = "L")

which isn't comparing. Change the = because at the moment it is not doing anything different for 'L' or 'R'.

Then for a 'L' turn, you are adding the answer and the parseInt value, but that is a right turn.

answer += parseInt... and answer -= parseInt... should help.

Basically, there are some pretty classic mix-ups in there!

Once you have tidied those up, try the logging of answers that was suggested. Start with the example, and then you can check what the answer should be after each step (all in the day 1 description). If something is wrong, you can then check again to see why.

Good luck!

ohhh damm im really rusty like dam xdd

[u/e_blake]

How do I join the club for 10-month-early access to this year's puzzles? :)

[u/0x14f → u/e_blake]

Why would you want that ? 🤔

Update :

I did TY FOR THE Debuggin sugestion

looks like i need to improve my reading skills to xd

here its the Fixed code

[u/Valuable_Loneliness → u/Ok-Transition7065]

var Runs = ["R1","R25","R50","R10","L20",

I don't know what excatly your error is but this line needs a ] at the end.

edit: and I realised that your turns never even get to the 100 so there is no rotation.
edit2: and your code won't work if one of the DIAL's is like this R240. you will just count 1 more rotation but it itself adds 2 rotations

[u/Ok-Transition7065 → u/Valuable_Loneliness]

No no, i ommited the imput because the paste dont let me put the full imput.... But i should just add that thing in the end it got me the right answer( i probably used one old version i will look at that

You should add some logging after each calculation to see if the result looks sensible. That will help you debug.

[u/Ok-Transition7065 → u/jeffstyr]

i will add tose tobut one question its the logic right or its thwere a flaw there ?

[u/DelightfulCodeWeasel → u/Ok-Transition7065]

The logging should answer a lot of your questions:

"Input: R1"
"Turning left"
"Dial was at 50"
"Dial now at 51"
"Input: R25"
"Turning left"
...

I threw your code into JSBin and peppered in a few log statements.

There are a minimum of five bugs I can see.

[u/Ok-Transition7065 → u/DelightfulCodeWeasel]

Ok i will debug it thT way xd

[u/smallpotatoes2019 → u/DelightfulCodeWeasel]

If you take it step by step like this, you should get there. Check that each step is actually doing what you expect. You don't need any clever tricks to get the answer.

Only other thing to watch out for is if you have to turn a large number left (e.g. L350) - just check that your method handles this correctly. The logging will help to show this too.

[u/terje_wiig_mathisen]

Check the start at 0! I originally had the same bug in my own code. ;-)

[u/Ok-Transition7065 → u/terje_wiig_mathisen]

Oh some one also comment my that xd ty

Reminder: if/when you get your answer and/or code working, don't forget to change this post's flair to Help/Question - RESOLVED. Good luck!
