How to center SVG in nextJs with viewbox

I am building a preloader using nextjs, it's a timed benzene animation that plays out entirely before the homepage appears. The issue that I am dealing with comes from both ways that I try to implement this preloader. First, when I set the viewbox attributes in the component as shown below, I receive an error.

"use client";
import React, { useEffect, useState } from 'react';
import './Preloader.module.css';


const Preloader = () => {
  
  const viewBox = `${-window.innerWidth / 2} ${-window.innerHeight / 2} ${window.innerWidth} ${window.innerHeight}`;

  return (
    <div className='preloader-div'>
      <svg viewBox={viewBox} width="100%" height="100%">
        ...
      </svg>
    </div>
  );
};

export default Preloader;

This is the error I receive...

error - ReferenceError: window is not defined
    at Preloader (./src/app/preloader/preloader.tsx:13:21)
   6 | const Preloader = () => {
   7 |   
>  8 |   const viewBox = `${-window.innerWidth / 2} ${-window.innerHeight / 2} ${window.innerWidth} ${window.innerHeight}`;

So I did some research, and there are a few ways that I would be able to fix this, and the one that worked the best was to use useEffect. It does remove the error but the issue now comes from my svg starting in the top left of the browser for about the first second of the page loading, but then when useEffect runs, it gets moved to the center.

"use client";
import React, { useEffect, useState } from 'react';
import './Preloader.module.css';


const Preloader = () => {
  
  const [viewBox, setViewBox] = useState('');

  useEffect(() => {
    setViewBox(`${-window.innerWidth / 2} ${-window.innerHeight / 2} ${window.innerWidth} ${window.innerHeight}`);
  }, []);


  return (
    <div className='preloader-div'>
      <svg viewBox={viewBox} width="100%" height="100%">
        ...
      </svg>
    </div>
  );
};

export default Preloader;

How would I remove this error but also have my svg centered from the initial loading of the page?

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...

Sorting large arrays of big numeric stings

I was solving bigSorting() problem from hackerrank: Consider an array of numeric strings where each string is a positive number with anywhere from to digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array. I know it works as follows: def bigSorting(unsorted): return sorted(unsorted, key=int) But I didnt guess this approach earlier. Initially I tried below: def bigSorting(unsorted): int_unsorted = [int(i) for i in unsorted] int_sorted = sorted(int_unsorted) return [str(i) for i in int_sorted] However, for some of the test cases, it was showing time limit exceeded. Why is it so? PS: I dont know exactly what those test cases were as hacker rank does not reveal all test cases. source https://stackoverflow.com/questions/73007397/sorting-large-arrays-of-big-numeric-stings
