Making an array with unique numbers

[thendal]

Hey guys!

Iam trying to make an array values as unique.

for example iam having an array

@a=(1,2,3,4,4,5)

I need an output @a=(1,2,3,4,5);

I tried like this.

for($i=0;$i<@a;$i++)
{
for($j=$i+1;$j<@a;$j++)
{
if($i eq $j)
{
splice(@a,$j,1);
}
}
}

using this i got the output 12345


But when i change the array values to some thing like this

@a=(1,2,3,4,4,4,4,4,4,4,5)

its giving an output not with the unique values

@a=(1,2,3,4,4,4,5)

I know iam missing some where in logic ,I hope u can help me.

I'm flattered you thought my solution was good enough to go into a FAQ. I got the idea from the perlfunc man page description of the map function. (You all have read the perl man pages, haven't you?)
