I have a string. $a="2A2B2C". The values of A,B,C are stored in an array @p=(1.5,2.5,3.5). The result of $a should be like this: (AA)*(50/100) (BB)*(55/100) (CC)*(60/100). The values of A,B,C should be repeated according to the adjacent number before that character. I may be wrong somewhere in the coding. The answer should be 28.4238 where as i am getting 2.165625. Here is the code which i used: 
$a="2A2B2C";
@p=(1.5,2.5,3.5);
#print substr($a,0,1);
#print "\n";
$b=length($a);
print "$b\n";
for($i=0;$i<$b;$i++){
$a=~s/(\d+)(.)/$2 x $1/ge;
}
#print $a;
for(1..$b)
{
if(1==$_)
{
$c=substr($a,0,1);
$r1=$p[0]*(50/100);
print $r1;
}
elsif(2==$_)
{
$c2=substr($a,1,1);
#print "\n$c";
}
elsif(3==$_)
{
$c3=substr($a,2,1);
$r2=$p[1]*(55/100);
print "\n$r2";
}
elsif(4==$_)
{
$c4=substr($a,3,1);
#print "\n$c";
}
elsif(5==$_)
{
$c5=substr($a,3,1);
$r3=$p[2]*(60/100);
#print "\n$r3";
}
elsif(6==$_)
{
$c6=substr($a,5,1);
#print "\n$c";
}
}
$answer=$r1*$r2*$r3;
print "\n$answer";
