RegEX help (working but need an exclusion) : I am need of some regex help.

I have a list like so:

/hours_3203

/hours_3204

/hours_3205

/hours_3206

/hours_3207

/hours_3208

/hours_3309

/hours_3310

/hours_3211



I am using this regex to find all entries that start with 32 or 33

    /hours_3[23]/

and this is working...

however I was thrown a curve ball when I was told.. I need to EXCLUDE 'hours_3211' from matching in this list..

How can I adjust my regex to match on all 'hours_3[23]' but NOT match on /hours_3211?



Alternately....

when I have a list like this:

/hours_3412

/hours_3413

/hours_3414

/hours_3415

/hours_3516

/hours_3517

/hours_3518

/hours_3519


I have been using a regex of:

    /hours_3[45]/

to find all 'hours_34x & /hours_35x

how I can adjust this:

    /hours_3[45]/

to find the above but ALSO find/match on /hours_3211??


thanks!
