First time working with any type of graph traversal. The algorithm determines whether a path exists between two nodes using breadth first searching (BFS). The BFS method has a tuple return type indicating whether a match has been found along with length between the two nodes. I implemented it thi...
I am trying to make a function to move an item in an array from one position to another, and shift all the other items to fill the gap. Here's what I have so far:
void MoveItemInList(unsigned Index, unsigned NewIndex) {
register const unsigned char Temp = List[Index];
if (Index < NewIndex...
I asked a question. I cannot separate it on independed questions, because the components are forming whole architecture(I think, that context is important here). But someone sayed(see second comment), that I need to insert code into the question(only this code can be reviewed, he said), but I can...
I recently wrote a mathematical expression parser in C++. The software can read valid mathematical expressions and evaluate them. An example of an expression the code can parse is (sin(pi)*e^(-3)). I would love to receive constructive feedbacks if possible for the code for compiler optimizations,...
Is there a more efficient way to do the following?
Basically, I am creating a NAME column in a dataframe and set its value based on substrings contained in another column:

As more fully detailed in my question here, I'm in the process of starting a small, local business and wanted to avoid showing sequential invoice IDs to clients, and instead generate completely random ones. Thanks to the advice in the comments to that question, I decided to eliminate the risk of ...

I want to understand if i got the concept correctly.
I should start work from ViewState (Reference type object holding the state of a view). Here it is called PageIndicatorVM. It is bad-to-impossible to have any internal state in a View
No logic in the View or so they say. Yet here and there in ...
This piece of code does a linear generation with two 'tweaks':
1:
it sets a global loop as an index to reference variables that are holding values that need to be exclusive to that value of loop. These variable are those using pointers and double pointers. That way we can play on the loop value ...
I wrote a script to execute a service on the Forestry TEP platform via its REST API. This service has certain input parameters, some of them are numerical values, other strings or files. The current workflow is:
