Write a function to accept an integer and return a number made up of digits from the input number in ascending order. : Write a function to accept an integer and return a number made up of digits from the input number in ascending order.
Also, If the input is a negative, then the change the order to descending.
For example,
if the input is 48455, the output should be 44558.
if the input is -15243, the output should be -54321

React-Navigation: Use/Change header title with Redux state : <p>Is it possible to access the whole Redux state inside the React Navigation's header title?</p>
<p>The <a href="https://reactnavigation.org/docs/intro/headers" rel="noreferrer">official docs</a> says that the state corresponding to the navigation is accessible:</p>
<pre><code> static navigationOptions = {
title: ({ state }) => `Chat with ${state.params.user}`
};
</code></pre>
<p>But I wish to access other parts of my Redux state, with the title updating when that state updates. Is that possible today?</p>

React useEffect Hook when only one of the effect's deps changes, but not the others : <p>I have a functional component using Hooks:</p>
<pre><code>function Component(props) {
const [ items, setItems ] = useState([]);
// In a callback Hook to prevent unnecessary re-renders
const handleFetchItems = useCallback(() => {
fetchItemsFromApi().then(setItems);
}, []);
// Fetch items on mount
useEffect(() => {
handleFetchItems();
}, []);
// I want this effect to run only when 'props.itemId' changes,
// not when 'items' changes
useEffect(() => {
if (items) {
const item = items.find(item => item.id === props.itemId);
console.log("Item changed to " item.name);
}
}, [ items, props.itemId ])
// Clicking the button should NOT log anything to console
return (
<Button onClick={handleFetchItems}>Fetch items</Button>
);
}
</code></pre>
<p>The component fetches some <code>items</code> on mount and saves them to state.</p>
<p>The component receives an <code>itemId</code> prop (from React Router).</p>
<p>Whenever the <code>props.itemId</code> changes, I want this to trigger an effect, in this case logging it to console.</p>
<hr>
<p>The problem is that, since the effect is also dependent on <code>items</code>, the effect will also run whenever <code>items</code> changes, for instance when the <code>items</code> are re-fetched by pressing the button.</p>
<p>This can be fixed by storing the previous <code>props.itemId</code> in a separate state variable and comparing the two, but this seems like a hack and adds boilerplate. Using Component classes this is solved by comparing current and previous props in <code>componentDidUpdate</code>, but this is not possible using functional components, which is a requirement for using Hooks.</p>
<hr>
<p><strong>What is the best way to trigger an effect dependent on multiple parameters, only when one of the parameters change?</strong></p>
<hr>
<p><em>PS. Hooks are kind of a new thing, and I think we all are trying our best to figure out how to properly work with them, so if my way of thinking about this seems wrong or awkward to you, please point it out.</em></p>

Submit POST form when rvest doesn't recognize submit button : <p>I would like to submit the following form (the form appears after you click on link "Kliknite na ..."):
<a href="http://www1.biznet.hr/HgkWeb/do/extlogon" rel="noreferrer">http://www1.biznet.hr/HgkWeb/do/extlogon</a></p>
<p>I have to enter one parameter, named "OIB" and submit the form by clicking "Trazi".</p>
<p>Here is my code:</p>
<pre><code>library(httr)
library(rvest)
sess <- html_session("http://www1.biznet.hr/HgkWeb/do/extlogon")
search_page <- sess %>%
follow_link(1)
form <- html_form(search_page)[[6]]
fill_form <- set_values(form, 'clanica.cla_oib' = '94989605030')
firma_i <- submit_form(search_page, fill_form, submit = 'submit')
</code></pre>
<p>Last line produces an error:</p>
<blockquote>
<p>Error: Unknown submission name 'submit'. Possible values:
clanica.asTextDatumGasenjaTo, clanica.asTextUdr_id</p>
</blockquote>
<p>I don't understand why rvest recognize this two parameters as submit buttons when they don't contain submit name or type. And why rvest doesn't recognize submit button "Trazi" as submit parameter? In, short, how to change filled form to execute the form?</p>

Ruby gem, color codes and string interpolation : I am trying to create a Ruby gem to colorize text. I am having hard time with string interpolation and color codes.
Say I want blue text
puts "\e[34mThis is blue text.\e[0m"
That's the way I get it.
I am using the "define_method" metaprogramming technique to create multiple methods(one for every color). The methods are created just fine, but I keep the color code for each color in an array. I iterate over both the color array and the color code one, and I do this
puts "\e#{code}m[#{self}\e[0m"
When I run it I get
"m[test" instead of the colorized text.
Any thoughts? If instead of #{code} I put the actual code, it works just fine, but that'd be like 20 ifs, one for each color and it won't be DRY.
Thank you. | 0debug |

Flutter: Should I use Bloc, or should I use redux? : <p>Hello I am new to flutter and is intertwined if I should use Bloc for State Management or redux. I am having a restaurant POS app where I state management is a must. I have a good experience with redux but Bloc has been recommended for flutter. </p>
<p>My Question is:</p>
<p>1.) Should I switch to Bloc or remain using redux where I am comfortable?</p>
<p>2.) What would be the pros and cooons of the two?</p>
<p>3.) Which of the are more scalable and mantainable?</p>

Route object validation as props in React : <p>What is the correct way to validate route props in React class?</p>
<p>I tried:</p>
<ul>
<li><code>route: React.PropTypes.object</code> - my eslint complains: <em>Prop type
<code>object</code> is forbidden react/forbid-prop-types</em> </li>
<li><code>route: React.PropTypes.instanceOf(React.propTypes)</code> - this results in a
warning at runtime: <em>Right-hand side of 'instanceof' is not callable Check the render method of bla</em></li>
</ul>
<p>We have the policy to validate props enforced by eslint rules, how can I validate route object?</p>
<p>My code: </p>
<pre><code>var bla = React.createClass({
displayName: 'bla',
propTypes: {
route: React.PropTypes.object,
})
class RootRoute extends React.Component {
render() {
return (
<Router history={hashHistory}>
<Route path="/" component={bla}/>
</Router>
);
}

spark dataframe drop duplicates and keep first : <p>Question: in pandas when dropping duplicates you can specify which columns to keep. Is there an equivalent in Spark Dataframes?</p>
<p>Pandas:</p>
<pre><code>df.sort_values('actual_datetime', ascending=False).drop_duplicates(subset=['scheduled_datetime', 'flt_flightnumber'], keep='first')
</code></pre>
<p>Spark dataframe (I use Spark 1.6.0) doesn't have the keep option</p>
<pre><code>df.orderBy(['actual_datetime']).dropDuplicates(subset=['scheduled_datetime', 'flt_flightnumber'])
</code></pre>
<p>Imagine 'scheduled_datetime' and 'flt_flightnumber' are columns 6 ,17. By creating keys based on the values of these columns we can also deduplicate </p>
<pre><code>def get_key(x):
return "{0}{1}".format(x[6],x[17])
df= df.map(lambda x: (get_key(x),x)).reduceByKey(lambda x,y: (x))
</code></pre>
<p>but how to specify <strong>to keep the first row</strong> and get rid of the other duplicates ? What about the last row ? </p>

The VBA documentation is poorly structured : <p>How to understand the VBA documentation? The documentation is poorly structured. For example, there are various libraries such as Microsoft Internet Controls and Microsoft HTML Object Library. But if you look for information about the contents of these libraries by their name, you will not find single (or main) pages of these libraries. The data is scattered and there is not a single page with content titles to the required libraries. If I'm right in this aspect, then it's terrible. I have experience programming in Python in terms of data analysis and there the information is clearly structured by libraries (the main thing is to know the name of the required libraries). Hence several questions.</p>
<p>1) What is the most effective way to find the necessary VBA documentation for specific libraries?</p>
<p>2) Am I right that the VBA documentation is poorly structured?</p>

.babelrc configuration placed in package.JSON : <p>Currently exploring webpack different tools associated with it. Now I am using Babel for transpiling <code>ES6</code> code into <code>ES5</code> code. I came accross the need for a <code>.babelrc</code> file which holds the configurations for Babel. However, on the website of Babel I also saw that you could also place these configurations into the <code>package.json</code> file. Like this:</p>
<p><strong>Package.json File:</strong></p>
<pre><code>{
"name": "webpack-tutorial",
"version": "1.0.0",
"description": "",
"main": "app.js",
"scripts": {
"dev": "webpack --mode development",
"build": "webpack --mode production"
},
"author": "",
"license": "ISC",
"devDependencies": {
"babel-core": "^6.26.3",
"babel-loader": "^7.1.5",
"babel-preset-env": "^1.7.0",
"webpack": "^4.16.2",
"webpack-cli": "^3.1.0"
},
"babel": {
"presets": [
"env"
]
}
}
</code></pre>
<p>Now when I run <code>npm run dev</code> Babel also works and the code gets transpiled succesfully. </p>
<p>How does Babel know to access the package.json file? Does it first look for an <code>.babelrc</code> file and then if this is not present does it automatically look for its configurations in the <code>package.json</code>? How does Webpack interact with both <code>Babel</code> and the <code>package.json</code> file to produce this result?</p>

Numeric to Date in R Excel Central Time : I cant seem to find the answers to this, I have tried multiple things - I am still very new to R
I have two variables in a dataset "Old Data"
"Open Date" - num from Excel and
"Closed Date" - POSIXct, format: "2017-10-11 12:39:37"
I can't get them to subtract for each line within the dataset, the conversions seem to be off
This is what I am trying to do (without the syntax

<p><code>tmp</code> is of the type <code>T*</code>, the new operator is being defined by <code>#include <new></code>, and I don't define the comma operator anywhere.

Javascript Substring missing characters? : I am trying to use substring to differentiate between data in java script.
The raw data I am pulling is:
0.! 3.0011632!
0.01! 2.9417362!
The code I am using is
var lastPosition = 0;
var count = 0;
//This code will continue looking for ! until it reaches three occurances
while (count <3) {
console.log(lastPosition);
console.log(contents.indexOf("!",lastPosition+1));
console.log(contents.substr(lastPosition+1, contents.indexOf("!",lastPosition+1)));
lastPosition = contents.indexOf("!",lastPosition+1);
count++;
}
The problem is the output I am getting is:
0 //start
3 //end
0.! //#
3 //start
14 //end
3.0011632! //#
14 //start
23 //end
0.01! 2.9417362! //#
As you can see its not properly locating the ! at the third cycle. This continues with more data and it eventually starts missing more and more !'s. Can anyone tell me what I'm doing wrong here? | 0debug |

When is the parent class variables available to use in Python? : <pre><code>class frozen(object) :
isFrozen = False
print 'In base'
class layer(frozen):
print isFrozen
</code></pre>
<p>I am trying to understand the inheritance concept in Python, the above lines are a silly example. "print" statement in the parent class is working as I try to create an object of layer class. But it's throwing an error at the "print" statement of the child class. Saying "isFrozen" is not defined.</p>
<p>But, if I comment out the "print" statement in child class, I can create an object of the child class and access "isFrozen" as "layerObject.isFrozen".</p>
<p>So, could anyone please point out my misunderstanding here? </p>

Need help, specifically with removing repeated word in list : I need to develop a program in which it takes in a user inputted string, e.g. ‘to be or not to be’. Then separate the string into its separate words, ‘to’, ’be’, ’or’, ’not’, ’to’, ’be’. The words are then put into a list, [‘to’, ’be’, ’or’, ’not’, ’to’, ’be’] where they are changed into their position in the list. However, if a word is repeated, only the first use of the word is counted and replaced with its position number. So, for example, both ‘to’s in ‘to be or not to be’ will be counted as 1. This is because the word ‘to’ is repeated and so the first appearance of ‘to’ accounts for both of the words. After the words are replaced with their position number, the sentence should be recreated with these numbers. So ‘to be or not to be’ should become ‘1, 2, 3, 4, 1, 2’. The list of both words and numbers should be saved as either separate files or one single file.
This is all i have so far:
UserSentence = input('Enter your chosen sentence: ') #this is where the user inputs their sentence
UserSentence = UserSentence.split()#.split()takes the inputted string and breaks it down into individual words...
#... and turns it into a list
List1 = UserSentence
List2 = UserSentence | 0debug |
How to read string in C : I try to run this code in c and expected runtime error but actually it did run,can you tell me the reason?
char str[10];
scanf("%s",str);
printf("%s",str);
As i initialized the size of array as 10,how can code prints string of more than 10 letters? | 0debug |

Find and draw the largest contour in opencv on a specific color (Python) : <p>Im trying to get the largest contour of a red book.
I've got a little problem with the code because its getting the contours of the smallest objects (blobs) instead of the largest one and I can't seem to figure out why this is happening</p>
<p>The code I use:</p>
<pre><code>camera = cv2.VideoCapture(0)
kernel = np.ones((2,2),np.uint8)
while True:
#Loading Camera
ret, frame = camera.read()
blurred = cv2.pyrMeanShiftFiltering(frame, 3, 3)
hsv = cv2.cvtColor(blurred, cv2.COLOR_BGR2HSV)
lower_range = np.array([150, 10, 10])
upper_range = np.array([180, 255, 255])
mask = cv2.inRange(hsv, lower_range, upper_range)
dilation = cv2.dilate(mask,kernel,iterations = 1)
closing = cv2.morphologyEx(dilation, cv2.MORPH_GRADIENT, kernel)
closing = cv2.morphologyEx(dilation, cv2.MORPH_CLOSE, kernel)
#Getting the edge of morphology
edge = cv2.Canny(closing, 175, 175)
_, contours,hierarchy = cv2.findContours(edge, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE)
# Find the index of the largest contour
areas = [cv2.contourArea(c) for c in contours]
max_index = np.argmax(areas)
cnt=contours[max_index]
x,y,w,h = cv2.boundingRect(cnt)
cv2.rectangle(frame,(x,y),(x+w,y+h),(0,255,0),2)
cv2.imshow('threshold', frame)
cv2.imshow('edge', edge)
if cv2.waitKey(1) == 27:
break
camera.release()
cv2.destroyAllWindows()

Java Scanner won't read through the whole file : <p>So I'm trying to read through a whole file and print its content, which it does. But when I go through it again with a new Scanner to print the content with some section names, it only goes through some of the file.</p>
<p>Here's my code:</p>
<pre><code>import java.util.*;
import java.io.*;
public class FileReader {
public static void main(String[] args) throws FileNotFoundException {
Scanner read = new Scanner(new File("sample.txt"));
while(read.hasNextLine()) {

}
System.out.println();
Scanner read2 = new Scanner(new File("sample.txt"));
int numQuestions = read2.nextInt();
System.out.println("Numbers of questions: " + numQuestions);
System.out.println();
while(read2.hasNextLine()) {
int points, numChoices;
String question, answer;
if(read2.next().equals("TF")) {
points = read2.nextInt();
System.out.println("Points for TF: " + points);
read2.nextLine(); // must be done because it does not consume the \n character
question = read2.nextLine();
System.out.println("Question for TF: " + question);
answer = read2.next();
System.out.println("Answer for TF: " + answer);
}
else if(read2.next().equals("SA")) {
points = read2.nextInt();
System.out.println("Points for SA: " + points);
read2.nextLine(); // must be done because it does not consume the \n character
question = read2.nextLine();
System.out.println("Question for SA: " + question);
