That's an unconventional way to write a 2-digit year, so I would expect that case to be explicitly called out in the description if that were the intent. I mean, for that matter, the description didn't explictly state that the digits are always in base-10, but you don't find my solution problematic because it doesn't handle input such as "A8F4", do you?

At any rate, I will defer to the test suite, which is the ultimate arbiter for questions such as these.

It could be interpreted that way, but with "0055" it is possible

Year = 55 is not part of the input domain. See the kata description.

Bad solution. Gives "1th" for year=55 instead of "1st"

Very clever! I did not know you could do that in rust

No, it's not a tie:

• P1: A pair with 7, 6, 4 kickers
• P2: A pair with 7, 6, 5 kickers

As the kicker 5 outranks 4, P1 loses.

See: https://en.wikipedia.org/wiki/Kicker_(poker)

According to the rules of Texas Hold 'em, if both player have the exact same class (except high cards), the highest of the unused cards is relevant (aka the kicker).

c++

This should result as a Tie, as both have Ace pairs, and both have the same kicker (7)

The unclarification of these rules is simply a burden for the solvers.

In c++ the reversed of this problem is true: The kata states that low aces are not valid, but it does checks on the test
