I guess this is what you actually want:

printf("%s%s",A[i],i<len ? " " : "\n")

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.
