Request your help in finding duplicate element without sorting

import std.format : format;
import std.string : strip;
int main (string [] args)
{
bool [string] found;
string [] result;
foreach (s; args [1..$]) {

if (t == "")
continue;
if (t in found)
stderr.writefln!"Duplicate element found: <%s>"
("element name");
else {
found [t] = true;
result ~= t;
}
}
result.writeln;
return 0;
}
```
```
$ ./remove-duplicates " test3" "test2 " " test1 " " test1 " " "
Duplicate element found: <element name>
["test3", "test2", "test1"]
```
