I know output to the console is a costly operation. In the interest of code readability sometimes it is nice to call a function to output text twice, rather than having a long string of text as an argument.
For example how much less efficient is it to have
System.out.println("Good morning.");

Here is the Problem
Extend to Palindrome
Problem code: EPALIN
Your task is, given an integer N, to make a palindrome (word that reads the same when you reverse it) of length at least N (1 <= N <= 100,000). Any palindrome will do.
Easy, isn't it? That's what you thought before you passed it on...
This is my first solo Objective-C program... it does the complicated task of displaying a button and counting how many times it's been pressed. It retains that count (along with the last time it was pressed) between uses of the app. I have a few specific questions, but eagerly await any and all...
I recently started using Builder pattern in one of my projects and I am trying to add some sort of validations on my Builder class.
Below is my builder class -
public final class DataKey {
private final long userId;
private final String uuid;
private final String deviceId;

Generics appeared in C# 2.0; in VB6/VBA the closest you get is a Collection. Lets you Add, Remove and Count, but you'll need to wrap it with your own class if you want more functionality, such as AddRange, Clear and Contains.
Collection takes any Variant (i.e. anything you throw at it), so you'l...
June is about to end. Summer's here (well, if you're in the northern hemisphere, that is.. otherwise, ... yay, winter!), and with it, vacations. We need a new community-challenge.
Let's play. I mean, let's find a game to play.
The game...
Has to revolve around reviewing code, or posting code ...
Problem: Display minimum number of characters to be removed from a string so that it becomes a palindrome.
Input #1: abc
Output #1: 2
Input #2: abb
Output #2: 0
My python code is as below:
# Checks whether a string is palindrome
def IsPalindrome(str):
m = int(len(str) ...

I need to find all paths from a given graph. I can do that for now, however my recursive code is not efficient also my graphs are very complicated. Hence I need a better algorithm.
def findLeaves(gdict):
# takes graph and find its leaf nodes
leaves = []
for endNode in gdict.iterkeys(...
Flags and Flag-flags:
Everytime your Variable name includes flag, there should be a flag raised in your head. You then should go back and either extract a method or a class.
Usually a flag means you are trying to do two different things in one method and that's something you shouldn't. Instead ...
I tested with your code and it works normally with me.
Now I changed the code a little bit :
Removed the extends SelectorComposer from your viewmodel cause that is not needed for MVVM.
Changed your 2 templates to 1 template.
Usage of your boolean in your viewmodel in the zul.

One may also solve for the generalized barycentric coordinates: at least one of them must be negative for points outside the convex hull of the polytope, see for example this thesis on On Generalized Barycentric Coordinates...
