Since strawberries and blueberries

[kexej28769@nongnue]

To make a salad with my favorite fruits (strawberries, blueberries, apples, and watermelon) I need to create a REGEX that matches all of them. Easy! Since the pipe character "|" means or I can do this:

REGEX 1: Strawberry|Blueberry|Apple|Watermelon
The problem with this expression is that REGEX also belgium number data partial matches, and since pineapple also contains "apple", it will be selected too... and I don't like pineapple!

To avoid this, I can use the other two special characters I mentioned earlier to create an exact match for apple. The caret "^" (starts here) and the dollar sign "$" (ends here). It would look like this:

REGEX 2: strawberry|blueberry|^apple$|watermelon
The expression will select exactly the fruit I want.

But let's say for the sake of demonstration that the fewer characters you use, the cheaper the salad will be. To improve the expression, I can use the qualifier for partial matches in REGEX.

A both contain "berry" and no other fruit is on this list, I can rewrite my expression like this:

Optimized REGEX: berry|^apple$|watermelon
That's it - now I can get my fruit salad with the right ingredients and at a lower price.
