That is best practice not nonsense in top....

Nicest method lol

This article (https://levelup.gitconnected.com/two-number-sum-in-golang-355627d6c861) describes the problem with this implementation, but I simplify the example to easily understand.

^ is bitwise exclusive or

It compares corresponding bits in two numbers. It sets the corresponding bit in the output to 0 if the two corresponding input bits are the same and 1 if the bits are different.

See: https://wiki.python.org/moin/BitwiseOperators

what is this ^ symbol ?

Gorgeous, thank you

It could be a suggestion but not the issue of the kata.

That's correct! See my fork that fixes the issue.

Also, this should be specified in the description and reenforced in the tests.

Cheers

i dont agree with this solution.
If you got an r = 0 in your param like I do, this solution fail

very well，I first know there are a class named fractions

What weird language is that ?!?

I'm sure most beginners are not aware that a bool is a subtype of int (True = 1 & False = 0) so a hint in the description will save some headaches.

Not an issue

There is a testcase that has a word that starts with a number.
