• there's a dummy JS version unrelated to the actual rust kata (please delete it)
• asking users to not use .rev() is just asking for users to do exactly that
• the function name provided in the initial code isn't correct

Add random and edge case

I have added sample tests.

I have removed the JS version.

On a second look at the problem statement of https://www.codewars.com/kata/60e4dfc1dc28e70049e2cb9d, they are different @Voile.

i have resolved it

I apparently don't have the permission to delete this Kata. What do I do next?

👍

And anyways, this kata is a duplicate of https://www.codewars.com/kata/60e4dfc1dc28e70049e2cb9d

Your test code is completely broken:

error[E0428]: the name `test1` is defined multiple times
  --> src/lib.rs:26:5
   |
19 |     fn test1() {
   |     ---------- previous definition of the value `test1` here
...
26 |     fn test1() {
   |     ^^^^^^^^^^ `test1` redefined here
   |
   = note: `test1` must be defined only once in the value namespace of this module

error[E0412]: cannot find type `string` in this scope
 --> src/lib.rs:1:25
  |
1 | pub fn max_depth(input: string) -> u8 {
  |                         ^^^^^^ help: a struct with a similar name exists (notice the capitalization): `String`

error[E0425]: cannot find value `output` in this scope
  --> src/lib.rs:29:38
   |
29 |         assert_eq!(max_depth(input), output);
   |                                      ^^^^^^ help: a local variable with a similar name exists: `outpu`

Some errors have detailed explanations: E0412, E0425, E0428.
For more information about an error, try `rustc --explain E0412`.
error: could not compile `challenge` due to 3 previous errors


NOTE: Line numbers in error messages can be incorrect due to concatenation.

There are no sample tests.

There's a dummy JS language version. You need to delete it from the editor.
