I have a sring like
$string = "abcdefghi";
i need to reverse the string in place i.e without using any other array or built-in function.
The algorithm used for this is swapping the numbers like below:
<code>
function reverse_in_place(a[0..n])
for i from 0 to floor(n/2)
tmp := a[i]
a[i] := a[n - 1 - i]
a[n - 1 -; i] := tmp
</code>
Can you please tell me is there any regular expression that can be used to reverse the string or any perl code will be helpful. Thanks in advance.
