Is it possible to reverse a string letter by letter using only regular expression?

I am learning string manipulation. Learned a bit about

string

string

and

StringBuilder

StringBuilder

. Now onto

Regex

Regex

and I'm trying to do everything which I do with string methods and StringBuilder methods by using Regex alone for learning purposes.

But reversing a string letter by letter seems pretty hard by just

Regex.Replace(intialString, pattern, replacement)

Regex.Replace(intialString, pattern, replacement)

I guess pattern can be:

string pattern = "."; // Match every character except new line

string pattern = "."; // Match every character except new line

But how to replace it

initialString[len - i - 1]

initialString[len - i - 1]

with

initialString[i]

initialString[i]

character of the string

initialString

initialString
