always check the description, thank you.

The first value is what your function returns, not the input value. Your function isn't returning the next bigger number, it's returning the biggest.

Hi. (python)
7210 should equal 2071
441 should equal 414
and there are more many issues with another numbers, why this happens ?

I am sorry, I am not that fluent in JS, but using proper formatting for your code might help others to read it and give some advice.

Thanks for answer ) can you check my code ?I have no ideas for this )

Having numbers 1234567908 and 1234567980, which of these two comes next after 1234567890? Isn't it that
1234567890 < 1234567908 < 1234567980?

Not a kata issue, 738 IS the next bigger number with those digits.

387 < 738 < 783 < 837 < 873

       |          you propose this one
      right expected value

Hello, I'm having this issue using Python :
-Testing for 387
---It should work for random inputs too: 837 should equal 738

I don't understand the result should be 837 and not 738.

I'm having similar issues using Python
