I have been experimenting around to generate all the n-combinations of an array. Below is the code to quickly generate all \$\text{k-combinations}\$ of a given array. I am testing my own implementation because of some restrictions in coding competitions (Also, knowing basics never hurts :)). """...

This question is a follow-up of a previous question of mine: Genetic Drift Simulator. Following the advice given in the last question, and some more general improvements, the code has been slimmed down a bit. The major one was implementing Underscore.js, which slimmed down a few of the loops int...

When I make an app using SQLite for local storage I've settled into a nice routine. Create a contract class and a extended BaseColumns class to hold column names and the functions for my all my CRUD db access needs. And of course extend SQLiteOpenHelper and with all of the create table and drop t...

Hi I'm wondering whether anybody would be willing to review this code for a game I'm working on with my friends.

Let's say I have an application (written in either C, C++, Fortran, or Python) which essentially works as follows: // Initialization: Setup data structure // Repeatedly work on data structure for (int k = 0; k < kmax; k++) { // Solve equations and store results in data structure } // Final...

I've got the following code. I want to loop through my dataset (which is a matrix) in steps of let's say 50.000 and perform biglm on it. lengthdata <- 100340 stepsize <- 50000 for (i in seq(1, lengthdata, stepsize)){ if(i+stepsize > lengthdata){ ## call function (i, lengthdata) pri...

I've build simple application that allows me to generate all numbers that have desired length and start with prefix. For example if I specify 12 as prefix and set desired length to 4 it will generate numbers from 1200 to 1299. I'm storing all generated numbers in List<int> then using shuffe metho...
