My problem is quite similar to the question found here, except I am attempting to answer the question in Python.
Performance of Codility MaxCounter challenge solution

# write your code in Python 2.7
counters = [0] * N
max_count = 0

ycoords = [y for y in range(y2, y2, dash_length)]
xcoords = [x1] * len(ycoords)

xcoords = [x for x in range(...
Here is my code which tests whether a given string has unique characters. The function is_unique which does a linear search for each character in the string is O(n^2) (if I am right). Is there any more efficient way of doing the same with more efficient DS that takes less time (or space)?

After the tips from my previous review. I have come up with these changes:
Separation of Concerns
Use Delegates
I'm asking you guys it this looks good. Other then separate out the FileButton_Click(), WriteResultsToFile(), and PromtSaveAsFileName() functions to another class would you recommen...

I have this code in JS, but think somewhere is more that is needed, can some some check it please and make his remark?

// Create pretty checkboxes ...
This is part of a series of algorithmic lessons and tests by Codility.
For copyright reasons, I cannot reproduce the question, but I can link to it here.
The question requires a response in O(n) time complexity. My response (below) was detected as O(n*log(n)) by Codility, but I have no idea why...
I have a Python class which defines various methods for connecting to a remote service and perform various API calls against that remote service.
Over the time my class got extended a lot and got lots of new methods for performing various operations against that remote service.
Currently I am t...
I have a folder with a lot of PDF,excel and word files. I would like to develop an ASP.net application that enables the user to search by text in available inside pdf,excel and word and bind file in grid using the content provided by them inside a textbox.
Any thoughts on how to make this script http://jsfiddle.net/BobanStanojevic/7p392tkt/ more reusable and ready for general implementation. Thanks
I have very little experience in programming with C++ and the following small "program" is the 2nd one I have ever written in that language. I am most interested in comments regarding naming conventions and the way the code is modularized. Also, can you tell whether the code sticks to idiomatic u...
I'm playing around with prototypes, constructor functions and javascript - I'm not really a Javascript developer but am interested in this.
So my question, am I on the right track with this code - Im looking for a code review from a js developer. I know the codes a bit funky.
I created an examp...
The ElectricalEngine class responds to the horsepower message. Because efficiency is calculated in percent a programmer can mistakenly initialize it with an integer instead of a float.

I am currenly contributing to a Chat-Bot to be used across the whole SE-Network's chat which is implemented in Java 8.
This bot is supposed to have commands. These commands again are supposed to be as flexible as possible, and based on chat messages. To allow easy and extensible implementation o...
It horrifies me to say this, but I think you didn't add enough padding.

Is there any problem in assigning Integer to int?
int x= Integer.class.cast(parameters.get("PO_PAGE_CNT"));
As Integer is the parent class and int is the instance, I think maybe in some cases I get ClassCastException or other type of Exception at run time. Is it right?

#include <time.h>
#include <math.h>

So, I'm not an expert JS programmer but there are a couple of things that can be improved.
Naming
I would encourage you to declare and name classes in the following way:
var ClassName = function(arguments) {...}
Having a capital letter for the class name helps it to stand out against standar...
I want to create a modeless popup dialog in VBA 7.0.
So far the most promising route seems to be CreateDialog.
First I tried CreateDialogW and received Entry point not found for CreateDialogW in DLL.
After opening the DLL, I verified this function was not listed. The MSDN reference linked abov...
This function takes a numeric vector and returns "con" if it's continous and "bin" if it's binary.
It does not take the multinomial case into account, i.e. if a variable y has three possible values 0, 1, 2, it's treated like a continuous variable.
Code:
checkBinaryTrait = function(v, naVal="N...
Signal-to-Noise ratio
Take this with a grain of salt, I realize your teacher might actually have made that a requirement. Generally, comments should not be used to describe what the code is doing, as the code itself does a pretty good job of doing that itself. Comments should be used to explain ...
sometimes when I write a python 3.x code with too many nested loops and some big values it just takes too long to give the answer. so my question is how to optimize my code so that it run faster or where should I learn optimizing?
for example:-

I have an array like Original = {1, 2, 3, 6, 7, 8, 9, 10, 12}. After removing some elements like Delete = {6, 7} from it, I want to get n sequential numbers which are not in the array, like IDs = {4, 5, 6, 7, 11, 13, 14, ..., n}.
After getting the numbers I want the original array to be changed ...
