Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target.
You may assume that each input would have exactly one solution, and you may not use the same element twice.
You can return the answer in any order.
Example 1:
Input: nums = [2,7,11,15], target = 9
Output: [0,1]
Explanation: Because nums[0] + nums[1] == 9, we return [0, 1].
Example 2:
Input: nums = [3,2,4], target = 6
Output: [1,2]
Example 3:
Input: nums = [3,3], target = 6
Output: [0,1]
Constraints:
2 <= nums.length <= 104
-109 <= nums[i] <= 109
-109 <= target <= 109
Only one valid answer exists.
Follow-up: Can you come up with an algorithm that is less than O(n2) time complexity?

Привет! Response от API приведен ниже. Мне нужно написать такую программу на python, которая будет определять текущее время по UTC+05:00, день недели (week_day=1 в ответе API означает понедельник) и текущую неделю (при условии, что первый день первой недели - 28 августа 2023). После этого код должен находить в ответе текущую неделю и близжайшее занятие (по времени, т.е. если сегодня 7 утра первого дня 29 недели, то близжайшее занятие - Экология и устойчивое развитие (Green Class) в 08:00-09:20 в аудитории 9-205).
Вот ответ API:

Привет! Помоги мне переписать код так, чтобы отображался еще и вид занятия (практика, лабораторная работа и т.д." ) и преподаватель.
Вот код:

}
response = requests.get(url, headers=headers)
if response.status_code == 200:

closest_lesson = lesson
return closest_lesson
next_lesson = find_next_lesson(today_lessons, now)
if next_lesson:
print(f"Ближайшее занятие: {next_lesson['schedule_subject_title']} в {next_lesson['schedule_time_title']}, аудитория {next_lesson['room_title']}")
else:
print("На сегодня занятия уже закончились или нет занятий.")

у меня есть подобного вида код "- --Decompiled Nodes-File 'Z:\decompiled nodes.dnf' automattically generatet from APE!

--The numbers in the single segements are:
-- PosX PosY PosZ LinkID NodeID PathWidth NodeType FlagInteger(UINT32)
cars = {
segment0 = {

if not manifesto_chunks[i]['text'][-1] in '.!?':
manifesto_chunks[i]['text'] += ' ' + manifesto_chunks[i+1]['text']
manifesto_chunks[i]['cmp_code'] += '+' + manifesto_chunks[i+1]['cmp_code']
del manifesto_chunks[i+1]
else:
i += 1
return manifesto_chunks
No the problem is that there a cases in the data which are complete sentences but just dont end with an sentence ending symbol. These are in the result super long of course. I want to end the concatenation for a given chunk when it exceeds 2000 characters

iv trained a model on my dataset like:
from sklearn.model_selection import GridSearchCV
from xgboost import XGBRegressor
# Initialize the XGBoost model
xgb_regressor = XGBRegressor(objective='reg:squarederror', tree_method='gpu_hist')
# Wrap XGBoost model with MultiOutputRegressor
multioutput_regressor = MultiOutputRegressor(xgb_regressor)
# Define the parameter grid for XGBoost
param_grid = {
'estimator__n_estimators': [400,800], # Number of trees
'estimator__learning_rate': [0.2,2], # Step size shrinkage used to prevent overfitting
'estimator__max_depth': [8,16], # Maximum depth of a tree
# Add more parameters here based on your needs
}
# Initialize GridSearchCV
grid_search = GridSearchCV(estimator=multioutput_regressor, param_grid=param_grid, cv=3, n_jobs=-1, verbose=2, scoring='neg_mean_absolute_error')
# Train the model using grid search to find the best hyperparameters
grid_search.fit(X_train_scaled, Y_train_scaled)
# Print the best parameters and the best score
print(f"Best parameters: {grid_search.best_params_}")
print(f"Best score: {grid_search.best_score_}")
how can i see mae of model performance on test and dev set?

══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
The following assertion was thrown during layout:
A RenderFlex overflowed by 38 pixels on the bottom.
The relevant error-causing widget was:
Column
Column:/lib/screens/quizz_screen.dart:49:22
The overflowing RenderFlex has an orientation of Axis.vertical.
The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and
black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the
RenderFlex to fit within the available space instead of being sized to their natural size.
This is considered an error condition because it indicates that there is content that cannot be
seen. If the content is legitimately bigger than the available space, consider clipping it with a
ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex,
like a ListView.
The specific RenderFlex in question is: RenderFlex#35fad OVERFLOWING:

make proper changes so the model uses "Open", "High", "Low", "Close","volume_base", "volume_crypto", "tradecount" instead of just using "Close" and also predicts "y1","y2","y3" instead of just Close price

Statement
You're given the buildings and the layout of roads between the buildings. Each existing pathway connects two distinct buildings bidirectionally, and there can be at most one pathway between any two buildings. Your objective is to determine the minimum number of new pathways needed to ensure anyone can travel between any two buildings in the Vindhya complex. Additionally, you need to specify which specific new pathways should be constructed.
Input Format
The first line will contain the two space-separated integers:
the number of buildings and
the total number of pathways.
lines follow, the
will contain two space separated integers:
and
indicating that the
road connects the buildings
and
Output Format
In the first line output
the minimum number of roads that need to be added.
Then, in
separate new lines, print the two buildings
and
, the buildings which your
new road connects.
If there are multiple solutions, print any of them.

<header><h1>Games</h1></header>
<p>Games are used to gain points. These appear in all Functioner and FunkOS systems.</p>
<h1>Types of games</h1>
<ul>
<li><b>Hidden Logo/Functosh</b>: Functioner or FunkOS gives you points if the mouse pointer hovers over its logo or icon (depending on the line of systems you're running).</li>
<li><b>Screensaver</b>: A item will appear on the screen and will go to random positions. If you manage to catch the item, you will then receive a 500 point bonus.</li>
<li><b>Screensaver New</b>: Only appearing in Functioner 96 to 10.10 by the time being, in CrypŁfunk and in FUNK/S. A item will be floating on the screen and bouncing. Press space if it touches the red area to receive the 500 point bonus.</li>
<li><b>Searchlight</b>: Similar to Screensaver. Only appearing in FunkOS Iⵔ+ by the time being. However, the item (called Functosh in FunkOS) moves around the screen instead of randomly appearing in random positions. It also leaves a trail.</li>
<li><b>Multiplayer</b>: Only appearing in FunkOS systems from Functosh System 1 to FunkOS 1ⵔIII and in FUNK/S by the time being. You are controlling the Functosh and have to defeat the opponent Functosh who blocks balls. If you shoot the ball to the opponent Functosh, you get a 500 point bonus.</li>
<li><b>Screensaver Soporose</b>: A new game mode. Only appearing in Functioner 11+ by the time being. Same as Screensaver, except the item doesn't move and appears in random positions before fading out and hiding into a different position, making it hard to play the game mode. You can find information about this one in the <a href="sillythings.html">Silly things</a> page.</li>
<li><b>Multiplayer Soporose</b>: Only appearing in FunkOS II+ by the time being. Same as Multiplayer, except the ball doesn't move and appears in random positions before fading out and hiding into a different position, making it hard to play the game mode, like in Screensaver Soprose. If the blue Functosh touches the ball, it will go to a different position far away from the blue Functosh.</li>

<header><h1>Silly things</h1></header>
<p>Discover quirky facts related to the amusing vocabulary within the Functioner world:</p>
<!-- Trivia: Dead pixels -->
<img src=“silly.png” height=“250px”>
<p><strong>Dead pixels:</strong> A dead pixel is a picture element in which all three RGB (red, green, blue) sub-pixels are permanently off, making it appear as a black spot on the screen. This term humorously reminds us of the frustrations of early computer users.</p>
<!-- Trivia: Image popups -->
<img src=“silly2.png” height=“250px”>
<p><strong>Image popups:</strong> The term “popup” dates back to the early days of web browsing, referring to unsolicited browser windows. It’s funny to see Functioner using an old annoyance for whimsical purposes.</p>
<!-- Trivia: FunkOS -->
<img src=“silly3.png” height=“250px”>
<p><strong>FunkOS:</strong> Perhaps a playful nod to various operating systems with “OS” in their names, implying functionality but here with a ‘funky’ twist emphasizing quirkiness or odd features.</p>
<!-- Trivia: Googly eyes -->
<img src=“silly4.png” height=“250px”>
<p><strong>Googly eyes:</strong> These are small plastic craft supplies meant to imitate eyeballs, where the pupil moves inside the larger clear sphere filled with liquid. Adding them to the FunkOS 8 logo certainly adds a lighthearted absurdity.</p>
<!-- Trivia: Complains -->
<img src=“silly6.png” height=“250px”>
<p><strong>Complains:</strong> In anthropomorphism, objects or software “complaining” about tasks they cannot do breathes life into them, suggesting a quirky personality for Functioner.</p>
<!-- Trivia: Classic mode -->
<p>In gaming and software, the term “classic mode” often refers to original or traditional gameplay features, pointing to a nostalgia factor within the Functioner ecosystem.</p>
<!-- Trivia: Screensaver -->
<img src=“silly5.png” height=“250px”>
<p><strong>Screensavers:</strong> Originally designed to prevent phosphor burn-in on CRT and plasma computer monitors by blanking the screen or filling it with moving images. The evolution into game modes showcases technological advancement with a nod to their origin.</p>
<!-- Trivia: Remote 3.6 -->
<img src=“silly7.png” height=“250px”>
<p><strong>REMOTE 3.6:</strong> The term “server system” is a technical designation for systems primarily used for running server applications. Its classification as a “consumer system” in-game adds an amusing contradiction, considering the professional and technical connotations of the term.</p>
<!-- Trivia: CPU Names -->
<img src=“silly8.png” height=“250px”>
<p><strong>CPU Names (“N1”, “N2”, “O1”, “O2”):</strong> These designations are typically used in computing to refer to “CPU cores” or “network operations.” By assigning simplistic labels, it playfully simplifies the complex nature of CPU architecture or network roles.</p>
<!-- Trivia: Azure and Tomato -->
<img src=“silly9.png” height=“250px”>
<p><strong>Azure and Tomato:</strong> These color names, often found in fancier design or art contexts, are humorously applied to multiplayer game modes, poking fun at the sometimes pretentious naming of colors in technology and design.</p>

I9K is a website that was created in April 2023 as <a href="https://i4k.neocities.org">Inter4000</a>, or I4K. It aims to provide high-quality content and resources to the I9K community and is powered by the company who also powers C159 and the pBar 63 homepage: <a href="https://iserver.neocities.org">iServer</a>. I9K is based on Clippy 159's site, and made after few more sites like <a href="https://ptfifou2.neocities.org">PTFiFOU</a>, <a href="https://i8kreturns.neocities.org">I8K Returns</a> and <a href="https://i8k.neocities.org">I8K</a>.
</p>
<p>Also, I do Functioner 95. You can see its wiki <a href="/Functioner/index.html">here</a> or explore the Functionnet <a href="/Functionnet/index.html">here</a>.</p>
<p>Functioner 95 (Public RC) can be downloaded here: <a href="https://file.io/Zp4mgmP1zGdT">https://file.io/Zp4mgmP1zGdT</a>. You have until 14 July to download it.</p> I make stuff and I am also managing Progresswire Coo right now.-->

<h2>About I9K</h2>
<p>I9K (or Inter9000 Returns) is a website that I created in April 2023, otherwise known as I4K before May 2023. Right now, I am working on it, and this website is powered by iServer (which is actually a seperate site of Clippy 159). Also, I am working on Functioner 95, which you can see <a href="/Functioner/index.html">here</a>.</p>

can you change this function to add an L.ImageOverlay rather than a marker. - // Function to handle square click and add a marker at the center for houses
function houseSquareClick(e) {
if (gridClickEnabled) {
var clickedSquare = e.target.feature;
// Get the center of the clicked square
var centerCoords = turf.centroid(clickedSquare);
// Get the bounding box of the clicked square
var bbox = e.target.getBounds();
// Get the southwest and northeast corners of the bounding box in pixel equivalents
var swPixel = map.latLngToContainerPoint(bbox.getSouthWest());
var nePixel = map.latLngToContainerPoint(bbox.getNorthEast());
// Calculate the width and height of the bounding box in pixels
var bboxWidth = Math.abs(nePixel.x - swPixel.x);
var bboxHeight = Math.abs(nePixel.y - swPixel.y);
// Define the custom marker icon with the calculated size
var customIcon = L.icon({
iconUrl: 'https://cdn.glitch.global/12fb2e80-41df-442d-8bf7-be84a3d85f59/_abb407dd-c75d-4d25-93bb-f07f25229da1.jpeg?v=1713688035687',

In NextJS, I have this form server action:
const [errorMessage, dispatch] = useFormState(authenticate, undefined);
<form action={dispatch}
When running with "next dev" it is working fine, but with @cloudflare/next-on-pages, I get a 404 POST error when I submit the form.

I have this form in NextJS 14:
import {authenticate} from '@/app/lib/actions';
const [errorMessage, dispatch] = useFormState(authenticate, undefined);
<form action={dispatch} className='space-y-6'>
This is the action:
export async function authenticate(
prevState: string | undefined,
formData: FormData
) {
try {
console.log('Hello world!');
await signIn('credentials', formData);
} catch (error) {
if (error instanceof AuthError) {
switch (error.type) {
case 'CredentialsSignin':
return 'Invalid password.';
default:
return 'Something went wrong.';
}
}
throw error;
}
}
However, after submitting the form, I just get a 404 error for the /sign-in path with the POST method.

I want to program the Political Compass plot from the Political Compass Test in Python with matplotlib. It should look exactly like the original Political Compass and I want to provide values for the social and enonomic axes to get a dot on the plot. The compass goes from -10 to +10 for both axis. Economic scale is the x axis, social scale the y-axis
