The code currently works as it should and seems to work dynamically as I need it to but I am pretty new to Excel so I think there is probably a better way to do some of the things I have set up. I also would like to make the code a bit prettier.

I am a beginner at coding in C#, hadn't had any experience with coding before and after beginning my learning I stated working on this calculator ahead that functions on the console. I'd like for you to please (if it's not too much to ask) review it and hopefully teach me what I could have done d...
Can you help me verify my test result? I'm testing different malloc implementations with a small program that allocates gigabytes many times:
int main(int agrc, char **argv) {
int i;
for (i = 0; i < 1000000; i++) {
void *p = malloc(1024 * 1024 * 1024);
free(p);
}

I've User and Notification Entity relation ship as

So the problem states that find out all the distinct possible ways there are to move from the first point (1,1) to point (n,n) in an n*n lattice.
So my code is:

list2 = []
my_list = []
for i in range(1, n+2):
list2.append(i)
for i in range(...
My program is supposed to sort a stack such that the smallest item are on the top. I can use a temporary stack, but you may not copy the elements into any other data structure. The program works overall, but I was wondering if there is anything that I can do to make it more efficient/better.

I have been tinkering with generic methods in java but still haven't figured out a way to optimize this code.

What I'm asking here is to verify my results, that multi-threaded (4 threads) merge sort is about 3 times as fast as single-threaded merge sort on a 4 or more core processor. The merge sorts are bottom up merge sorts.

Looking for criticism on JavaChat, a JavaFX chat program I made! Comments on better practices, organization, or anything you find I could improve on would be very useful, thanks!

As part of my own C++11 learning exercise I have implemented this Blocking Queue using the new C++11 thread API. One of the aspects I would like to improve is efficiency i.e. in the take member function while returning the Job template type to be returned by reference instead of by value.

I just started learning Haskell and this is my first big project (ie not factorials, fibonacci or graphers). This is kind of a gift for somebody so the language is a bit different. The program works, but I felt that some parts of the code could be improved, specifically:

Write a recursive function that returns 1 if a given string is palindrome in c#?
Normally, I don't anticipate exceptions and if I get them, its something that I can't fix in my code - bad user input or connectivity issues with the database.
But errors do occur so at the very least, I want to inform my user that something went wrong and log the error.

I've written a "simple" interpreter for a programming language in Python, called Tellurium (named after the element of the same name). So far, it's working pretty well, but there are some things I'd like to fix/remove.
The code can be found here.
The reason I posted this here is because the cod...

I am using numpy random choice np.random.choice(m, k, replace=False) to select k items randomly from a list and this is very time consuming if I have to run this step for 1 million transactions. I used cProfile and the above step was the culprit.

I realized I had just created two classes that were virtually identical for simply saving objects to their own json files, so I've attempted to make it more generic. My only noticeable problem is because I am using gson to serialize / deserialize, that requires an explicit class type, which gets ...
Below is my implementation of a generic linked list in swift. Unfortunately, swift playgrounds won't run until the compiler is totally happy - often, that involves clang making me explicitly unwrap some optionals. I just want a general idea of how to restructure my code to avoid unwrapping option...
As I did the same exercise some time ago, I used a different approach, using hashes. It takes advantage of the ability to define a default for hashes when accessing a not present element.
So, in general:
x=Hash.new
x[1]
#=> nil
but
x=Hash.new{12}
x[1]
#=>12
Now... what happens if I define t...

Recently, I encountered this coding exercise on codility and the idea is
