I highly recommend that you create a Tree interface that can be implemented by a BinarySearchTree class. Take your insert, delete, find, etc. methods and declare them over there. Suppose you decide to create a Red-Black tree, then you could create a RedBlackTree class which implements th...
It's easy to look at numbers; numbers tell us that many developers have been helped by what we built. That alone is very warming and makes us feel exceptionally great about what we're doing, wouldn't it be nice to take a little time on a Friday to share some stories that the numbers can't convey?...
In onion arch. we have multi layer structre:
UI (User interface).
BL (Business Logic / Services).
RE (Repositories).
UI uses BL to get data from RE with some conditions, my question is which is better approach (as standard) to get data from BL:
In Repository (Data Access Layer):

I'm getting my feet wet in embedded development, and like all those before me, my first task was to make an LED blink. I went a bit further than that and made a "runner" that lights up each led from 0 to 7 in sequence. The sequence begins as soon as the board is powered on. You can see it in acti...

I'm trying to use jQuery to dynamically alter a webpage. My goal is to do the following:
1: remove some content currently on the page
2: in timed intervals, append and fadeout/remove text
3: once 1 and 2 have completed, add a dropdown list for the user to select some stuff.
As I understand it,...
I'm a freshman in high school and I started a C++ programming class about two months ago. I have decided to go ahead of my class and study strings, conditionals, and flow control. Since then, I have begun creating my first text based video game, but I am having problems with a few bits of code.

Still oiling my Forth. Below are few essential algorithms for in-place merge. Please review.

I created the following cloud code to convert Images (links) into 'files' that Parse can store.
It works- but is incredibly slow for some reason. Can anyone help me review it and speed it up?

While the question could be better, I will speak of some points.
Naming of variable :
One of the most common bad habbit is declaring an int in the for loop as i.
It's not readable and you do have much better names for it.
I suggest naming like pointer or currentIndex.
possible bug :
if (x2 !=...

You are given N sticks, where the length of each stick is a positive integer. A cut operation is performed on the sticks such that all of them are reduced by the length of the smallest stick.
Suppose we have six sticks of the following lengths:

ROT13 ("rotate by 13 places", sometimes hyphenated ROT-13) is a simple letter substitution cipher that replaces a letter with the letter 13 letters after it in the alphabet. ROT13 is a special case of the Caesar cipher, developed in ancient Rome.
