I am trying to get an array of all regex matches. For example, something like this:
PATTERN: (\d+)[a-z]+
STRING: 123asd
RESULT: ["123asd", "123"]
^ ^
full capture group 1
Additionally, if there are multiple matches, it should continue matching, for exa...

I am solving one binary search problem in leetcode.
I have accomplished such code:
impl Solution {
pub fn search(nums: Vec<i32>, target: i32) -> i32 {
if nums.is_empty() {
return -1;
}
if nums.len() == 1 {
return if nums[0] == target { 0 } else { -1 };
}

I have a function that takes in a string and based on the string hits different api's to fetch images.
I have solved it by writing an interface and then as return type of the function it returns a Promise<Interface> as shown in code below.
interface IAnimal {
image?: string | null

The following is just a working example.
I have a DataFrame containings a monotonous growing function.
Some of the values are actuals, some are forecasted.
I need to filter specific actuals values based on a set of milestones and I have to avoid to take forecasted values from the dataframe

I made a snake game implementation in console with rust.
Would like to hear what I'm doing wrong and what can be improved.
main.rs

mod board;
mod game;
mod position;

pub const TAIL_SIGN: char = '#';
pub const HEAD_SIGN: char = 'O';
pub const APPLE_SIGN: char = '@';

So here's the problem
Given a 2D numpy array 'a' of sizes n×m . You need to pad the matrix
with 0s so that the dimensions of the matrix become (n+2n1)×(m+2m1)
a = np.array([[1, 1], [1, 1]])
n1 = 1
m1 = 2
print(padding(a, n1, m1))
>>[[0, 0, 0, 0, 0, 0],
[0, 0, 1, 1, 0, 0],
[0, 0, 1, 1, 0...

I've written a simple Hash Table implementation in C, in order to use it in an IRC bot, so mostly storing nicknames, channel names, etc (small strings). I'm using linear probind to resolve collision.
Here is the public API (hash.h):
#pragma once
#include <stdbool.h>
typedef struct hash {

I'm learning Rust by implementing basic data structures and algorithms. I implemented a binary heap (max heap):
mod binary_heap {

pub data: Vec<T>,
}
impl<T> MaxHeap<T>
where
T: PartialOrd,
{
pub fn new() ->...

How to make a generic version of my function with unlimited "keys". Please see the function below. It's a mockup for another function that I want to use. But I got stuck. I used switch just to hard code the actual output I'm after. So it's just to illustrate the issue. Sorry friends, I'm not the ...
This is based on this leetcode question please remove if that is not allowed. I get the correct answer, but I know it could be much, much cleaner. I also know there is supposed to be a O(n) space solution, but I'm not sure how to implement cleanly.
It is a dynamic programming problem, I tried t...

I have decided to make snake game as my first project with C++ (using OOP) and I didn't follow any tutorial while doing it, now I am frustrated and need to know if it the code is good or not and what can be improved in it?
