Note that the value of NR in END is sort of a gray area, but it works as
expected in GAWK, which is really all we care about.

Here's an even tighter version.  Saves about 20 bytes of code.
Yes, I know this code makes a lot of assumptions, but all the assumptions
are valid in the instant case (and that's all that matters):

{ A[$1] = $2 }
END {
    for (i=1; i<=NR; i++) $i = A[i]
    print
    }

Joni Ernst (2020): Trump is doing great things, because only 65,000 times as many people have died of COVID-19.

Josef Stalin (1947): When one person dies, it is a tragedy; when a million die, it is merely statistics.
