Im trying to write a program that will get three numbers from STDIN im calling them $x,$y,$z I need to call a sub- rootine that will find the lowest number of the three I thought if I sorted them then retrived the first number it would be snazzy but i cant figure out how to get only one number to print sub

sub lowest {

@array = ("$x,$y,$z");

print join(' ', sort { $a <=> $b } @array, "\n"); }

I've been staring at this code trying different aproches for days now any sugetions would be much appeciated
