I have written a code which is easy to understand but may not be efficient but will solve the purpose.

int ar[] ={1,2,3,4};

I really enjoy Haskell but feel I still have a total beginner's style, and would like to move beyond that. The code below - for Dijkstra's shortest path algorithm - is a case in point. I feel as though I have ended up with a copy of the imperative pseudo code I began with, having done some smal...
I am new to jMockIt and so wanted to learn it. I thought of implementing a synonym servlet kata. The servlet takes a word as input and returns the synoyms of the words as a comma seperated string. The objective of the kata that I implemented was:
Learning jMockIt stubbing and mocking features.

In a jPanel, I'm displaying a 1203x1203 background that I rotate every 30ms. Problem is, swing is known to be a slow library, and I assume rotating a huge picture at a quick rate would be quite resources demanding. But I've a powerful pc, and even if on mine it runs fine, I wonder if on slower ma...
Your solution relies excessively on magic numbers, such as 9 and 3. It also obscures the Cartesian Product aspect of the problem. Therefore, I think it could be better written as:
(< (< (< 4))) { ,/ > { (i:1) ,&< (i:1)
MonoGame is an open-source version of Microsoft's XNA. It's a framework for building cross-platform games.
It has a number of mathematical types such as Vector and Quaternion.
I am a bit baffled by they way they are using doubles and floats.
So far I have gathered the following information:

I have a comboBox and a TextBox in the View and when the view is loaded, the ComboBox should be populated. After that when a user selects particular item from the ComboBox, its related ValueMember should be displayed in the TextBox.
The View doesn't know about DAL or Presenter and, it only has ...
I have a method that transforms any input uint into [min,max] set. I am looking if I can improve the function, specifically to get rid of input == uint.MaxValue case.
public static uint NumberInRange(uint input, uint min, uint max)

decimal divider = uint.MaxValue / (decimal)max;
if (in...
Please take a look at this class and point out its flaws.
I am developing a simple Finite Element Method analysis with PHP.

Given an input set (coordinates, properties, plane type)
Calculate an output/analysis set (area, matrix, etc.)
Possible hints on flaws :

In this problem you are given input of phone numbers and you are supposed to determine whether any number is the prefix of another. I have an addchild method that returns true or false if a given string can be inserted and is not a prefix of another string. How could I improve the efficiency of m...
Could you please tell me if there is better way of performing division without +,* or /
I tested this code for different values of a and b.
Could you please tell me if there is a cleaner solution.

Extending on the ideas of others... Write a piece of code in a language that you don't know, which writes code into a language which you also do not know yet, all taken from an existing code review question, also coded in a language you do not know.
Do the ultimate challenge.
