O(n^2) It doesnt look like best practices at all in this case

done in JS, C

this is mint

you assign an unsigned int to a signed int when you do div= number;. as a result your calculations are wrong when number > INT_MAX.

I don't understand how this is supposed to be a challenge on rust, this is like 8kyu on rust

I think there're lots of fake users vote for this solution by best practice why ?

semicolons are optional in javascript, that's why it works. However, it would be cleaner to used them to be consistent within respective code. Or omit them everywhere.

Description should be language-agnostic

Haskell translation

The test cases require us to return a decimal number and this sounds like it's asking for a 32-bit number.

I think that your understanding of "decimal numbers" and "32-bit numbers" is not exactly right. Test cases do not require you to require "a decimal number", but just a number. Representation, decimal or any other, is irrelevant here. And 2149583361 can be described as "32-bit number" if it can be stored with 32 bits of information (which it can).

Final line of instructions could be rewritten to be less misleading...
"Because the above IP address has 32 bits, we can represent it as the 32 bit number: 2149583361."

Once I'd figured that out, I enjoyed it though - thanks
