Re: Terse Code for Odd Numbers

Basically same thing, just slightly different construct (half the iterations)

perl -le 'print map {$_*2+1} 1/2..13/2'
[download]

Update: Can just use 'for' instead of 'map'..

perl -le 'print 2*$_+1 for 1/2..13/2'

wait a second... 1/2 * 2 + 1 = 2/2 + 1 = 1 + 1 = 2 isn't that an even number? i think you meant: `perl -le 'print map {$_2+1} 0..12/2` [download] Update:* Nope, i was wrong. i started thinking about how to do this given a low and a high, so i got about this far: `int( $low/2 )..int( $high/2 )` when i realized, hey, the .. operator probably takes the int of the values already. so i tried it, and after running the code provided, i found out the .. operator already does take the int of the values, so your answer works. sorry.
