Every conversion I've tried so far results in -> "\u0086" where the tests require ->"\x86".
Casting with string(), converting with strconv and fmt.Sprintf all produce "\u0086".
Trying to create a new string results in "\x86".
Any hints you can give me ?
In Java I encountered no similar issue and solved it in a few minutes.
(Now that I can see the hidden issue, it's the same as my question)

I'm also fighting with the task, whatever I do I just cannot make it return the string literal rather than utf encoded string. (

Shit, solved, it was, actually, easy :)

I got this output (and failed the final tests) in exactly the same way because I was trying to use string() to cast a rune. In order to pass the randomized test, the code needs to be able to account for runes greater than a single byte.

I actually only had to make minimal changes to my code to pass the tests otherwise, so I'm leaving this for anyone else who may be tripped up by this - hopefully not spoiling too much :)

Thanks! I mark issue as resolved.

Found the problem and fixed it. Now your solution passes but are you sure that the product of two int64 is always an int64?-) Seems you are lucky since n and p are not very big here.
Tell me if you succeed and mark the issue as resolved if you do it.

"Mul" is in "math/big"; I import "math/big" in my solution and in the tests so I don't understand where the problem comes from. If you want you could put your solution (marking it as spoiler) and I will try to understand what happens. Do you pass "RUN SAMPLE TESTS"?

Don't you import "math/big" in your solution?

i've made those changed so you should order by day then department-name.
