*nix 'dc' guru needed
hello
googling, i found this 'wurst' (german for sausage)
Code:
2p3p[dl!d2+s!%0=@l!l^!<#]s#[s/0ds^]s@[p]s&[ddvs^3s!l#x0<&2+l.x]ds.x
it's a reverse polish formula to print PRIMES using *nix /bin/dc
so the cmd: (use bourn-sh, or mask metas)
echo "$sausage" | dc
will very fast AND endless print primes on stdout.
i'm quite familiar to '[bd]c' and 'reverse-polish'
but i cannot (in the exemple above) figure out, how to say:
start at X and stop at Y (sure X and Y are integers, 1+X > 0 && X < Y)
thanks for help
