I'm trying to solve the project Euler problem 54. The code works alright, but I'm interested in learning how I can improve its quality in any possible way.
from collections import Counter
suites = {
'C' : "Club",
'D' : "Diamond",
'H' : "Heart",
'S' : "Spade",
}
values = {

you shouldn't use the same incrementation variable twice in the same scope, it can get messy and cause weird bugs and you do it with two different incrementing variables, i and j.
uint64_t maxRoot = sqrt(max); // optimization #1
uint64_t i;
int j; // sieve multip...
I am a very beginning in PHP and Design Patterns. I have been studying the amazing Head First Design patterns. So, I have been trying to translate the original into PHP. The class is working well, however, I would like to ask:
Is this considered good PHP?
Someone mentioned that this is not a St...
I wrote a small component (still in the works but working) which takes a large SQL script file, splits it into different "blocks" based on GO statements, and executes them one by one.
The only major flaw I know of is not being able to detect when a GO statement is inside of a comment block, for ...
I want to create algebra evaluator but I don't want to write my own parser because it takes much time to learn.
I don't like algebra expression in C# because it does not look natural compared to VB counterpart. For example, "x^2+1" in VB must be written as "Math.Pow(x,2)+1" in C#.
I am still a n...
I have written a parallelized version of Gauss-Laguerre quadrature and am wondering how best to handle infinities that occur due to lack of floating-point precision.
Basically, I use Newton's method to approximately solve Laguerre polynomials in order to find the abscissae \$x_{i}\$ and weights...
I am trying to use ByteBuffer properly with BigEndian byte order format.
I have couple of fields which I am trying to put together into a single ByteBuffer before storing it in Cassandra database.
That Byte Array which I will be writing into Cassandra is made up of three Byte Arrays as describe...
I have the following header included in some of my projects so that I can add a little color to the terminal output. Here is how it would be used:
fprintf(stdout, "Recognized text: %s\n", text ?: RED_TEXT("No text recognized."));
color.h:
/**
* @file color.h
* @brief Defines all of the A...
I wrote this tiny script to pull the JSON feed from the CitiBike website.
Here is the script:
import requests
import time
def executeCiti():
r = requests.get("http://citibikenyc.com/stations/json")
print r.json()
time.sleep(62)
while True:
executeCiti()
exit()

Looks like most things are covered by the other answers.
I can only add that you should might want to use constant string pointers rather than literal strings--particularly if you ever use these same strings anywhere else.
@"FindBookMeeting" instead becomes:
NSString * const kFindBookMeeting =...
I created a simple application that downloads an image from a web API, then sets it as my desktop background. The entire project is exactly 100 lines of code, but I feel like it can be cut down significantly while still being easy to understand.
It is a console application, and closes immediatel...
While this is a good start, there are several things that should be noted.
r = requests.get("http://citibikenyc.com/stations/json")
This is code snippet is network-based, and so errors may occur. You will want to handle these errors in some way, with a try-except block like so:
try:
r ...
I can see both of your concerns. In a way I feel by doing this the asker robs himself of good aspects of CR that could only be tested by compiling/executing the code, such as performance issues.
I think it is one thing to remove potentially private data like passwords, server IP and such that c...
After a
UINT lSize;
GetRawInputDeviceInfo(hDevice, RIDI_DEVICEINFO, NULL, &lSize);
RID_DEVICE_INFO* lInfo = (RID_DEVICE_INFO*) malloc(lSize);
GetRawInputDeviceInfo(hDevice, RIDI_DEVICEINFO, lInfo, &lSize);
I get 9 devices: 3 mouse, 3 keyboards, 3 hid devices.
I have one mouse, one touchpad,...
Problem statement:
Input is a rectangular bitmap like this:
0001
0011
0110
The task is to find for each black (0) "pixel", the distance to the closest white (1) "pixel". So, the output to the above should be:
3 2 1 0
2 1 0 0
1 0 0 1
Below is a working, heavily commented 78 lines solution. ...
