It's great that you decided to share the Windows 98 activation keys, but you're a little late with the publication.

Testing this code, I found many cases where it gives the wrong result. Some examples:

Player hand - Opponent hand

JC TH 2D 2C 3D - 9D 4C 8S 8C 6C
Reported Win should be Loss: player's pair of 2 are beaten by opponent's pair of 8.

3C JH 5D JC 7D - AS 3D 4C 9D 3H
Reported Loss should be Win: player's pair of J beats opponent's pair of 3.

TH 9D QC 6C QD - 9H 2D QS 2H KH
Reported Loss should be Win: player's pair of Q beats opponent's pair of 2.

All the cases I've checked are similar in that both player's have a single pair.

hmmmmm...

Same, it's tragic that the testing framework's It macro makes including <range/v3/all.hpp> impossible. Any brevity you are able to achieve is offset by the gazillion lines of import above it :(

😄 Perfect C++20/23 !!

But you know what : I'm tired with 30mns trying to figure out which include I have to use in rangev3 for each algo/view/.. and line of code !!

😃

actually this is incorrect and will fail in some random tests, but it passed...

would you please give some explaination? XD

yes, just realized the sign bit and '\0', thanks for your reply

your buffer is not large enough, and as a result you are writing out-of-bounds and corrupting the tests suite.
note that printf("%d", INT_MIN) == 11

i got you must return the given string error msg in random test,

need i consider the realloc?
