Improved version:

{ A[$1] = $2 }
END {
for (i=1; i<=NR; i++)
printf("%s%s",A[i],i<NR ? " " : "\n")
}

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
}
