Hi! I wonder if rustc optimizes the two traversals into a single traversal? Does anybody know?

Would you mind to elaborate? It's almost the same solution in C.

I find it very funny that I'm always overthinking things having a C background, does anyone have any tips?

Can this one be approved?

PLEASE DON'T APPROVE

This forks adds some of the language descriptions, I don't know the missing languages.

DO NOT APPROVE

Changes things in description

TODO: insert all languages as examples

Honestly the whole description needs a little bit of massaging. It used to say returns array, but now it says returns tuple. Since the description last changed from wanting an array to wanting a tuple, the description is not correct for e.g. python.

It used to have the example snippet in one syntax and one syntax only. Now it has two languages specified despite many languages supprted. It will show hs for all others than elixir.

A Rust example should be added to the description.

Changes:

• Function signature to tuple as the description reads
• Tests from C++
• Some extra fixed tests for edge cases
• Resolve description merge conflict
• make do_test extra verbose when failing a test

From the description "... double are formatted with no decimal" so there is no "direct" rounding, only the use of "format!" or "write!".

Changed it.

There's no reason to allow incorrect results by using assert_floats_eq, multiples are integers, so precise results should be expected.

Fixed
