Yeah it's a dupe in JS

Needs everything :(

Test cases especially

Ok, just wanted to make sure, thanks.

For 2., do you mean in approx in the test cases?

JS Translation

Yeah, those were my thoughts exactly.

A<=B, not A>=B as described in code and description, please fix.

That explains a lot. Thanks for the feedback, someone already beat me to fixing it.

JS Translation

I had that issue. My error was because I had array's within the array (eg [1,2,3,[1,2],3]), and the test cases can't compare the values because of the multiple arrays inside of the array.

Wow! That image helps out a lot!

I kinda accounted for that. But yeah, calenders are dumb.

But if paxompaxom wanted to, he could do that and then use a random time generator.

Is there a chance that Feb 29th occurs in let date = new Date(2000, 0, Math.random() * 20 * 365 + 1 | 0).toISOString().slice(0, 10);?

Here's a random date generator I made so you can use an actual Date of Birth for the random tests. I made the year from 2000-2022, cow's have a life exepectancy of about 20 years.

var date = "";
var year = "20" + Math.floor(Math.random()*22).toString().padStart(2,"0");
var month = (Math.floor(Math.random()*12)+1)
var day = Math.floor(Math.random()*31)+1;
var hour = Math.floor(Math.random()*24).toString().padStart(2,"0");
var min = Math.floor(Math.random()*60).toString().padStart(2,"0");
if (month == 2){
    if (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0)) day = Math.floor(Math.random()*29)+1;
    else day = Math.floor(Math.random()*28)+1;
}
else if (month == 4 || month == 6 || month == 9 || month == 11){
    day = Math.floor(Math.random()*30)+1;
}
month = month.toString().padStart(2,"0")
date = year+"-"+month+"-"+day.toString().padStart(2,"0")+ " " + hour +":"+min;

// random outputs:
// 2003-12-18 13:42
// 2016-05-23 02:28
// 2010-10-20 02:24
// 2000-03-01 21:37
// 2008-08-06 11:58

Also, this part kidna confuses me.

Next, a string of the form <id><name><dateOfBirth> is formed from the fields - id, name, dateOfBirth. The name field is padded with spaces at the end of up to 10 characters.

The resulting string is converted into a byte array — each character of the string is assigned a corresponding ASCII code (a number from 0 to 255).

Is this just one string composed of all 3 forms combined (with name being a string with a length of 10)? Or is it 3 seperate strings?

Edit, I think I figured this part out. It's <[id]><[name]><[dateOfBirth]>. I recommend putting an example like <0123456789><wisper cow><2019-06-11 00:00>

Thanks! This will make it way easier for people to decode the image and know what they'll have to print.
