regular expressions

question 1

Create a regular expression that matches only the As of UQAM in a text, and no other A. You need to provide the best regular expression possible, not just a regular expression that might work in some cases.

Hint: There is a simple solution. Search carefully!

Question 2

Create a regular expression that matches all expressions starting and ending with the same word separated by at most 10 characters such as "la vie la" in "la vie la mort", or "no more not" in "no more not too much" .
