I asked the same question on StackOverflow but was told to instead ask here since it was better suited. I have a function that I implemented. It is doing a lot of heavy lifting. I would like to optimise it or in other words try to find repeating code and simplify it a little bit. I'll show my imp...

Given an array of integers, return the minimum required increment to make each element unique. Sample Input 1: [3, 4, 2, 2, 6] Sample Output 1: 3 (One of the 2s should be incremented to 5) Sample Input 2: [3, 4, 5] Sample Output 2: 0 (There is no duplicate) My code works in the linear time since ...

I wrote this reduce function and got comments on my pull request saying that mutation is not good practice, however, I only mutated the accumulator and I didn't see any benefit of creating a new object on every iteration. Following is the code, would be great to see what everybody thinks about th...

I have a nested if/else loop, and as you can see in the code below I have two different conditions but two times the same statements. Is there some way to code this is a more reusable way?

I'm trying to create a function to check multiple conditions of data. The function will return a list if the data is errors. Here is my idea: error_lists = [] def check(A, B, C, D, E): check condition 1 for A if there is a error -> error_list.append(1) check condition 2 for B if t...

I have a Asp.Net API (.NET Framework 4.7.2). We recently updated Autofac to version 6.2.0. Autofac does not like some of our classes that don't have a public constructor. Example class: public sealed class User { private static readonly Lazy<User> Lazy = new Lazy<User>(() => new User()); ...

I am solving a puzzle at codingame.com and I have to write a code that has at most 200 characters, now it has 772 counting tabs. Is it possible to do something with an input scanner so it takes less characters? The condition alone makes like 180 and don't worry about how a code looks like it's ju...

This code takes the already extracted leaf angles from 2D images and puts it into a dataframe. For some reason when I use the .median function to try to find the median for the first four leafs to returns 'NaN' even though there is values. Maybe it can't because it might be counting it as a tuple...

I was implementing the AAN algorithm for computing the 2D Discrete Cosine Transform on an 8*8 array. I perform both the forward and inverse AAN algorithms. My code is extremely fast compared to the naive DCT algorithm but I feel that my implementation could be faster. How can I improve the perfor...
