Answer 3

False. Within a character class, characters can be listed individually, or a range of characters can be indicated by giving two characters and separating them by a single dash as in [abc] or [a-c]. See Regular Expression HOWTO .

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
