In an attempt to solve a problem on Leetcode, I used dictionary and sets to have O(1) time complexity.
However, my speed is too slow, better than just the 5% of Python submissions.
Here is my code:
from typing import List
class ValidWordAbbr:
def __init__(self, dictionary: List[str]):

I am using Google's BigQuery API V2 on a custom Google Data Studio connector. The BigQuery.Jobs.query() calls take roughly 50 seconds, this is too long, so I'm looking ways to speed things up.
Sample code

// Cloud Platform project.
var projectId = 'XXXXXXXX';

I've been working on a little implementation of game of life, it works well with boards of size 20x20 or smaller, but when I try to increase the size it gets really sloppy. I never worked with threads, but if they increase performance I'm open to learning and researching about them.
Here is the c...
I have a large text file(~600 gb). File consist of float and/or int only.To sort data, I open the file and read line by line and then save my desired line into an array. At the end I saved my file. My code that I have tried so far,

Not sure the best way to solve this using recursion. Below is what I have tried so far:
public static void findSum(int[] a, int sum, int i, int j) {
if(i == a.length)
return;
if(j==a.length)
return;
sum = (a[i] + a[j] > sum) ? (a[i] + a[j]) : ...

I have a nested for-loop that looks like the following. The for-loop is used to scan a spatio-temporal (3D) cube and run a specific kind of cross-correlation used in seismology.
# some initialization

qp = np.sum(Pg1t[:-1,20:40,20:40],axis = 1)/20

I'm writing a C application for the Networking course at the University.
Basically it's a UDP server that can receive two commands:
GET key

That are executed against a Hash Table data structure.
I'm now writing the code that parses the string into a command struct, and the logic is...
The RPG Library (the ERD-model here) is used to create Prototypes of Monsters and Items. These prototypes will later be used to create Instance in my RPGGame. I do not have much (de facto: none) experience in ERD-Design, so i appreciate any help.

Sometimes I need to push data to the array, but I have one different key (here I have key color and key name) and another part of the object is the same. I use IF/else to check this, but i wonder is there any better and cleanest way to handle this?

I am currently taking back Python after over 6 years I do not use it, and to do that I am solving some small challenges on Hacker Rank. I wrote a code that works, but which is not performant and I would like to have some ideas to optimize it.

I am reaching my one year on programming and decided to create a simple pin and password program to better help me understand arrays. As far as coding standards, best practices, and functionality what else could I do to this to make it better?
