Pretty new to Rust, decided to brush up using the Advent of Code 2020 Day 1 Puzzle. I'm using the following function:

Answered 2021-Jan-18 at 21:19You can omit the return
keyword only if the returned value is the last expression in the function block, otherwise you need to explicitly use return
. Adding return
to your example fixes that particular error but a bunch of new ones come up in its place. This is how I'd write the function:

QUESTION
Is there any way to process a changing list using higher-order functions in Clojure and not using explicit recursion? For example, consider the following problem (that I made up to illustrate what I have in mind):
Problem: Given a list of unique integers of unknown order. Write a that produces an output list as follows:
- For any even integer, keep the same relative position in the output list.
- For any odd integer, multiply by ten, and put the new number at a new place: at the back of the original list.
So for example, from original vector [1 2 3 4 5], we get: [2 4 10 30 50]
I know how to solve this using explicit recursion. For example:
...ANSWER
Answered 2020-Dec-27 at 02:23This is much easier to do without recursion than with it! Since you only care about the order of evens relative to other evens, and likewise for odds, you can start by splitting the list in two. Then, map the right function over each, and simply concatenate the results.
QUESTION
Hello I'm struggling with copying an array into a middle of other bigger array. I don't see a reason why it shouldn't work even the indicies are correct. It's for https://adventofcode.com/2020/day/17. They ask for 3D array but I need to solve it with 2D array first.
I have an empty array like so
...ANSWER
Answered 2020-Dec-23 at 10:50You can try this logic:
- Create 2 variables:
midRow
: To hold x positionmidCol
: to hold y position
- Then loop over provided value array.
- Use
midRow
andmidCol
to calculate the position to write. - Override the value and print it

I'm trying to solve a puzzle of 'Advent of code', which entails finding out how many passwords are valid of a list of passwords and their policicy.
But my code returns always 627 instead 474, which is the official solution to my puzzle input.
Can someone explain what could be wrong?
The puzzle: AdventOfCode_2020_Day2
My puzzle input: GoogleDrive_PuzzleInput

Answered 2020-Dec-22 at 19:40Your nested loop condition is bad - your algorithm will never count more than the policy’s max value
QUESTION
I have been trying to solve Advent of Code 2020 day 13 part 2 task. I found a lot of hints talking about something called Chinese Remainder Theorem. I have tried some implementations following npm's nodejs-chinesse-remainders but this implementation since to be quite old (2014) and also requires extra libraries for Big Int cases.
How could I implement the modular multiplicative inverse ? How could I refactor the CRT algorithm define in the npm module for which I provided a link?
...ANSWER
Answered 2020-Dec-13 at 13:07As a self response and with the purpose of make a wiki to find this solution for those who in the future need a CRT implementation in javascript/typescript:
First think is to implement Modular Multiplicative Inverse, for this task what we try to find is an x such that:
a*x % modulus = 1

QUESTION
I got a git repository where I got several files. (Actually it's my Advent of Code repository)
In this repository is a file which I want to keep in the GitHub remote but I don't want git to update it, even if this file changes locally. Also I want this behavior automatically on every machine where I clone this repository to.
So basically these steps:
- Create file and add initial content (v1)
- Commit and push file to remote branch
- Do something that lets git ignore all changes to this file on every machine
- Change the file content (v2)
Now I got the file in the remote (v1) and locally (v2) but I don't want to see anything about this file when I run git status
. Also if I clone this repository (with file v1) to another machine and make changes to the file (now v3), I don't want to see anything in git status
about this file on the other machine.
To provide an example: I want to add the file which will contain my session cookie to GitHub. Obviously I don't want to push my session cookie to GitHub, just the a placeholder or something. But when I run the program, it must contain the right session cookie, so I have to update the file with the actual cookie. Now I don't want git to update this file to GitHub. And when I clone this repository to another machine, I want it to contain the placeholder like in the remote which I can then update manually. Also git should not want to update the file from this machine either.
First I tried adding it to .gitignore and running git rm --cached myfile
but then git wants to delete this file from the remote as well.
I tried with git update-index --assume-unchanged myfile
. Which technically does what I want, just not on all other machines because it only affects my local git repository.
Is there even a way I can accomplish what has to be done in step 3?
...ANSWER
Answered 2020-Dec-11 at 21:50You're asking how to ignore changes to a tracked file, and the answer is that Git doesn't do that. From the entry in the Git FAQ:
Git doesn’t provide a way to do this. The reason is that if Git needs to overwrite this file, such as during a checkout, it doesn’t know whether the changes to the file are precious and should be kept, or whether they are irrelevant and can safely be destroyed. Therefore, it has to take the safe route and always preserve them.
It’s tempting to try to use certain features of
git update-index
, namely the assume-unchanged and skip-worktree bits, but these don’t work properly for this purpose and shouldn’t be used this way.
Any sort of secret should be passed in through the environment or a config file. It's fine to create a template for this purpose and check that in, then have a script to copy it into an ignored location so that you can edit it and add the secret. For most major production systems, secrets are typically passed in through the environment so they aren't written to disk.
