The thing that looked the slowest was
int mask = 0;
for (int i = 0; i < depth; i++) {
int queen = candidates[queens[i]];
mask |= queen; // previous queens cover this column....
mask |= queen >>> (depth - i); // previous queens cover this

Task: Suppose you have the following:
class Thing {
public:
void foo (int, double = 3.14) const {std::cout << "Thing::foo(int, double = 3.14) called.\n";}
void goo (int, double = 1.5) const {std::cout << "Thing::goo(int, double = 1.5) called.\n";}
};
void function1 (const T...
I am building a small DSL for iOS' autolayout feature obviously I want to have a typesafe way to define autolayouts instead of doing VSL. I came up with the following
//in reality this will be a Xamarin/iOS View
type View =

type Constraint =
| Max of int
| Min of int

I have recently written this little Bulls and Cows game in Python:
"""Play Bulls and Cows."""
import random
NUM_DIGITS = 5
class IllegalNumber(Exception):
"""An exception to raise when the class Num has an instance of an
illegal number."""
pass
class Num(object):
"""Represent a...
In my college Java course, I wrote an ASCII Turtle Graphics. My professor said the only thing he could suggest was to turn the turtle into a class and create an instance of it (I hadn't because we hadn't covered classes yet). What do you think?

import java.util.Scan...
Below is a piece of code which takes a list of IPs, pings the hosts and returns (prints) the list for "Alive" and "Dead". Any feedback on what can be done better is welcomed! Mainly, speed and reliability! Would you accept it as a production code? try/except blocks, logging?
Cheers and Happy New...
Outside of the jQuery DSL I've hardly ever written any JavaScript. I never bothered learning JavaScript until a couple of months ago. After a slow start I got stuck in and created this game.
As some may know I usually program in Ruby. And this is proving to be a great obstacle because I'm instin...

This program transposes rows and columns for file contents:

for line in fin:
intermediate+=line.strip() + "\n"
i = intermediate.splitlines()
heading = []
values = []
splitstring = " "

The actual question: Is it okay to use reduce two times in a row on the same list? (it is not exactly the same list as it has been reduced, but I hope you get my point)
First of all I'm new to lisp (I currently use clisp and sbcl), there probably are huge mistakes in this code so any guideline...
I wrote a program that client can connect to server but server doesn't send files name to client. who can help i? this program must does this: first server send to client name of file for downloading. then client send to server name of file that it wants to download and then server send file to c...
When someone suggested me to solve Knight's Tour, I did so with backtracking and recursion.
It takes a lot of time to solve even a 8x8 board:
NA1
NC2
NE3
...
NC5
NA6
Time used to solve: 7079726 nanoseconds
That seems quite a lot, but the most interesting part of my algorith ...
I'm still very much a beginner, so I don't really know much about best practices or the speed of any particular C functions.
You'll notice that I included a "cs50" library --> this is from a MOOC I'm taking, all it does in this program is allow me to use their "bool" data type. I realize I don't...
