#include <vector>
//Calculates divisors
void Divisors(unsigned number, std::vector<unsigned> &result){

I want to check if a given string is a date of the form YYYY-mm-dd, including all the steps in it, i.e. YYYY-mm-dd, YYYY-mm and YYYY.
For example, all of the following dates are valid:
2014
2014-07
2014-07-03
This is my current regex:
^\d{4}(:?-\d{1,2}(:?-\d{1,2})?)?$
Is it OK?

This is a follow up to this question. I have taken the suggestions given to me and implemented them in my code, as well as moving towards adding more features to the program. I am unfortunately required to use a linked list for storing contacts, so I cannot adapt to your feedback for that, but thank you all for helping... | stackexchange/codereview |

I have started dabbling with golang. I wrote up a binary search tree implementation. I was wondering if there is a cleaner way. Here is my implementation:
type BNode struct {
left *BNode
right *BNode
data int64
}
func insert(n **BNode, data int64) {
if *n == nil {
(*n) = &BNode{data: data, le... | stackexchange/codereview |
Our solar system has 8 planets, including earth. Our calendar has some very confusing concepts such as leap years, which I still don't fully understand. In fact, since where I live, we use a different solar calendar that is different from the Gregorian reforms of the Julian Western calendar, I think I'm born in March b... | stackexchange/codereview |
This is my first attempt with a basic text adventure game, and I was wondering if there was a way to make it more efficient (or any other things I could add to make the game better). It isn't totally finished yet, but if there is a way to make it better, please post in the comments.

This is my implementation of the bell() function to calculate the n-th bell number in C.
Along with it I made the factorial() and binomial() functions.
I have serious doubts about their efficiency, in particular whether my implementation of the factorial() function should be correctly optimized for tail-recursion, and ... | stackexchange/codereview |
