Daily Challenge #78

Hello Koders :kodular:,

Bc nobody made today’s Daily Challenge, I thought to make it by myself.

Your task for today is to make a procedure which gets one input and has one output.

Rules:

  • input (number) will be taken as index for:
  • output (number) will be the digit (only one) number in this list:
    12345678910111213141516... and so on…

The real challenge is today, to make the list so long that it is as long as the input.

Examples:

  • input: 12 :arrow_right: output 1 bc:
    123456789101112… eleventh digit

  • input 25 :arrow_right: output 7 bc:
    12345678910111213141516171819… 25th digit

I hope you understood, this idea came to me from a math book for nerds :nerd_face:

@Yoshi

EDIT: Forgot to say, for proof of functionality, use these inputs:

10, 25, 0 and 1,000,000.

So the output would be a single number or list?

Like for example if input : 11 then will the output be 0 or 12345678910?

Hey check this out.
For this to get to work just provide any number using the text box and when button is clicked label1 text will be set to the number you are looking for.

Please add a spoiler or hide details immediately. Ok you add it.
Btw, my solutions

My solutions

Without using list (22 blocks)
(For me, it is the best solution among all my solutions)
DC #78 without YailList

With list (23 blocks)

With YailList
With YailList710×354 25.8 KB

With list (optimized, less lag than the upper one) (25 blocks)

DC #78 with YailList optimized
DC #78 with YailList optimized840×380 28.6 KB

Finally, this proof of functionality

Lags my entire phone.

So what should return?
This should return nothing/error, because in the list,

there isn’t the 0th number.

#11

Probably an empty string.

If so, then I need to debug and add more blocks (and that’s isn’t a good thing)

#13

But we will have to wait for reply from @Yoshi

I have made a solution using 16 blocks

Did 1 million (1,000,000) input lags your phone? I can’t even reach 20000

#15

Yes.I am also not able to get output.

#16

About 6 hours to go, for the “official” answer…

#17

So before we get ‘official’ solution , I would like to post my solution here.

blocks (46)

Note: It takes some time to get output for biggest numbers like 1,000,000 but it works normal for bigger numbers like 100,000

Yours is much simplier than me. Good Job! (idk why I was think of for each number before, but i used while test.

Wow! My phone cannot reach that. It is already 8GB RAM

Some studies say that for loop is faster and consumes less memory then while loop

:scream: :scream: :scream:
Maybe build an apk is better than companion?
I tried your solution, and I still can’t reach 100000
