I was solving Project Euler problem 16, which asks to find the sum of digits of the number 2 raised to the power 1000. Using Python, it can be solved in one line of code:
sum(map(int, list(str(2**1000))))
It felt too easy so I decided to write a function in C to do the same job. Here's my program. In what ways can I i... |

I wanted to write a simple Log class for PHP, I use ajax calls with AngularJS and often return the log in an array
Example:
$return['data'] = $returnedDataArray;
$return['log'] = $logDataArray;

echo json_encode($return);
I was hoping to implement a logging system in my other classes, lik... |
I'm a complete neophyte to Haskell with only a smidge of FP experience – I did some Racket programming academically and have written some semi-FP JavaScript professionally, but now I'm trying to learn Haskell (and FP better). So I read Haskell Fast & Hard with no problems up until the last chapter.
