I would appreciate improvements and suggesstions on my implementation. Here is the code - #include <iostream> #include <string> #include <stdexcept> // t...

I'm not an experienced programmer, this is my first programming language to learn. And I've come to a problem using Classes and Structures. The documentation says: Classes can do that and that, Structures can do that... etc. But when it comes to actually using them how do i know how to do it prop...

I have tried my hand with implementing simple quadrature formulas in C++. Definite integral: $$\int_a^b f(x) dx$$ Domain of integration \$[a, b]\$ divided into \$n\$ intervals of equal length \$h = (b - a) / n\$. Midpoint of interval \$h_i = b_i - a_i\$ is $$x_i = a + h / 2 + (i - 1) h$$ with \$i...

My Data consists of rows containing a Length/Duration in Minutes, a Begin & EndTime. The precision is 1min (or larger). the table looks something like that: CREATE TABLE public."TimeSeries" ( "Id" uuid NOT NULL, "BeginTime" timestamptz NOT NULL, "EndTime" timestamptz NOT NULL DEFAULT ...

This code works perfectly and I am getting back the results I expect. We were told to do this and any testing if necessary. I got asked this in an i...

I am currently working on a chess console app. However i feel like i got some inefficient code. For example: In order to find out whether an enemy is in check I start iteration over all pieces and all their possible moves. I am glad to get any advice regarding the structure syntax etc. on my proj...

I keep getting timed out. I think my general logic is right but how can my code be optimized more? I know there are solutions using the bisect module but I've seen very simple ones without using that. From what I can think of, maybe using while loops will speed things up? def climbingLeaderboard(...
