How to Match Repeated Characters in Go Regular Expressions Without Backreferencing?

Matching Repeated Characters in Go Regular Expressions

In the context of regular expressions, capturing repeated characters often proves to be a valuable technique. However, in Go's regular expression engine, backreferencing is not supported, making it impossible to directly match repeating characters as demonstrated in the given Javascript code.

To overcome this limitation, you can explore alternative approaches:

• Employ an Alternate Regex Library: Consider utilizing a third-party regex library that supports backreferencing, such as "glenn-brown/golang-pkg-pcre," to achieve the desired functionality.
• Implement Custom Logic: You can craft a loop that iterates over the input string and checks for repeated characters. This approach, albeit less efficient than using regular expressions, remains an option if regex libraries cannot be employed.

While Go's regexp package does not provide direct support for matching repeated characters, these alternative methods allow you to achieve the desired results in your code.
