This is my program currently to calculate sum of following series:
Here it is in c++:
#include <iostream>
using namespace std;
int main() {
int fac = 1, x, p = 1;
float sum = 0;
cout << "\nENTER x: ";
cin >> x;
p = x;
for(int i = 2; i <= 4; i++) {
fac *= i;
...
Here is a piece of C++ code that seems very peculiar. For some strange reason, sorting the data miraculously makes the code almost six times faster.
#include <algorithm>
#include <ctime>
#include <iostream>
int main()
{
// Generate data
const unsigned arraySize = 32768;
int data[arr...
It's 2015 already, folks, go home.
So, now that it's 2014, it's time for a code question involving the number 2014.
Your task is to make a program that prints the number 2014, without using any of the characters 0123456789 in your code, and independently of any external variables such as th...

Print a String by Flipping Bits

This challenge is loosely inspired by the unimplemented esolang Pada.
Consider an array of 8 bits, all initialised to zero. We'll introduce a very minimalistic instruction set to print arbitrary strings. There are two instructions, both of which take a...
