Perhaps algorithm 3 is more efficient, but algorithm 2 is decent and very easy to implement in Julia. So this solution uses algorithm 2.
 
<lang Julia>
<lang julia>function maxconcat{T<:Integer}(aarr::ArrayVector{T,1<:Integer})
b = sort(dec.(arr); lt=(x, y) -> x * y < y * x, rev=true) |> join
b = map(string, a)
breturn =try sortparse(bInt, lt=(x,yb)->x*y <catch y*xparse(BigInt, rev=trueb) end
b = join(b, "")
try
b = parseint(b)
catch
b = parseint(BigInt, b)
end
end
 
tests = {([1, 34, 3, 98, 9, 76, 45, 4],
[54, 546, 548, 60],
[1, 34, 3, 98, 9, 76, 45, 4, 54, 546, 548, 60]})
