Could you please share the link where I can read more about this solution)

You have a missing semicolon

@alexschrod awesome answer, thank you for explaining so succinctly

dang and I thought mine is simple enough

I know this is old, but can someone explain where the s comes into play?
I know the left side s is the parameter but the right side s is what is returned, but how does that return if the vale is true if there is only the parameter.

The problem with a random number generator is that it's possible for it to generate the same number twice in a row, which would cause you to drop the second packet.

The random number also won't help you if the packets ever get out of order - guaranteed never to happen in this Kata, yes, but probably not in any networks you might be designing for in the future.

This one was fun, I forgot about using sliding windows to search a matrix!

should explain in more detail what value is returned in the original clamp function (return the number input if the number falls within bounds else return either the lower bound or upper bound)
