c++ - Large Integer Division - Knuth's Algorithm D -


i have divide number (no matter size) number using large integer division using knuth's algorithm d (the art of programming volume 2), example 74839234 72548.

i made 2 arrays represent these numbers

n[] = {7,4,8,3,9,2,3,4} d[] = {7,2,5,4,8}

i trying output this:

q[] = {1,0,3,1} r[] = {4,2,2,4,6}

i don't know start this. or guidance appreciated!

at d1 have d=1, set 

n[]={0,7,4,8,3,9,2,3,4}

n = 5, m = 3.

also, there formal error in step d4: (second line) should ...

minus q(hat) times (v1, v2, ..., vn)b times b ** (m - j).

here, ** means "power of" (fortran style easy writing). of course, b = 10 here, so

times b ** (m - j) shifts subtrahend left, proper place subtraction.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
