Hi All,
Request your help in finding duplicate element without sorting
as per the below example
```
Example:
string[] args = [" test3", "test2 ", " test1 ", " test1 ", " "];
Output Required:
If duplicate element found then print "Duplicate element found:
"
else print ["test3", "test2", "test1"];
```
From,

```
import std;
void main() {
string[] args = [" test3", "test2 ", " test1 ", " test1 ", "
"];
findDuplicates(args);
}
void findDuplicates(string[] args) {
bool[string] dupes;
foreach (arg; args) {
if (arg in dupes) {
writefln!"Duplicate element found: %s"(arg);
return;
}
dupes[arg] = true;
}
writefln!"%s"(dupes.keys);
}
```
