Hi. I have a script here but it is not doing what its suppose to do. I am trying to make it so it sorts my array ascending. Here is the script.
#!/usr/bin/perl
@array = (5,3,2,1,4);
$i=1;
$a=1;
$s=1;
var1=0;
var2=0;
var3=0;
var4=0;
var5=0;
while($i < $#array) {
for($j=0; $j < $#array; $j++){
if ($array[$j] == $a) {
$var[$s]=$a;
$a=$a+1;
$i=$i+1;
$s=$s+1;
}
}
}
@array = ($var1,$var2,$var3,$var4,$var5);
foreach $elem (@array){
print "$elem";
}
