Re^42: Interleaving bytes in a string quickly

length works
reverse works

Funny definition of "works":

$a=''; $a .= chr 1<<$_ for 0 .. 63;;

print length $a;;
64

$a = reverse $a;;
Malformed UTF-8 character (byte 0xfe) in reverse

print length $a;;
75

In the absence of evidence, opinion is indistinguishable from prejudice.

I don't get that. `$ perl -le' > $a=""; $a .= chr 1<<$_ for 0 .. 63; > print length $a; > $a = reverse $a; > print length $a; > ' 64 64` [download] Maybe it's cause I'm on a 32-bit build? $a contains 0..31,0..31 and the reverse once reversed.	[reply] [d/l]
