Answer 1

You need to use boundary

\bre\b

---

With boundary you can match characters that are surrounded by non-word characters..

Simply put it \b around a word enables you to match an individual word

For example for string "Begin it in stackoverflow" and if you want to replace in with IN

in regex would replace it to "BegIN it IN stackoverflow"

\bin\b regex would replace it to "Begin it IN stackoverflow"
