java – Minimum number of swaps required to bring the queue to its final state, not exceeding 2 swaps per element

Scenario or problem definition:
It is New Year and everyone is ready for the roller coaster ride in Wonderland! There are a number of people in the queue, and each person carries a sticker indicating their original position in the queue. The starting positions are increased from 1 in front of the line to n behind the line by 1.

Any person in the queue can bribe the person directly in front of them to swap positions. When two people change positions, they still wear the same sticker that marks their original positions in a line. One person can bribe at most two others. For example, if n = 8 and person bribe 5 person 4, the queue looks like this: 1,2,3,5,4,6,7,8.

Fascinated by this chaotic queue, you need to know the minimum number of bribes that have taken place to bring the queue to its current state!

operation manual
Complete the minimumBribes function in the editor below. An integer must be issued indicating the minimum number of required bribes. If the line configuration is not possible, it is too chaotic.

minimumBribes has the following parameters:

q: an array of integers

input format
The first line contains an integer, the number of test cases.

Each of the next pairs of lines is as follows: – The first line contains an integer, the number of people in the queue. The second line contains space-separated integers describing the final state of the queue.

output format
Issue an integer that specifies the minimum number of bricks required to bring the queue to its final state. Too messy if the condition is invalid, d. H. If a person must have bribed more than persons.

Sample Input

5 1 2 3 7 8 6 4
1 2 5 3 7 8 6 4

example output

Too chaotic

Basically, I'm trying to create a method that will accept the values โ€‹โ€‹of the queue in this (final) state and return the number of bricks needed to get to the final state, starting with 1,2,3,4 , 5, … Indicate if the number of bribes per person in the queue is not more than 2. Otherwise "too messy".

The code that fails in some cases using Java streams is as follows. I want to know why I can not achieve the output with Java streams.

static void minimumBribes(int() q) {

        AtomicInteger bribeCount = new AtomicInteger(0);
        AtomicReference chaoticString = new AtomicReference();

        IntStream.rangeClosed(1, q.length).forEach(i -> {
            if (q(i - 1) > i) {
                if (q(i - 1) - i > 2) {
                    chaoticString.set("Too chaotic");
                } else {
                    bribeCount.addAndGet(q(i - 1) - i);

        if (chaoticString.get() == "Too chaotic")


The code passed without using Java streams is given below:

static void minimumBribes(int() q) {

        for (int i = 0; i < q.length; i++) {
            if (q(i) - (i + 1) > 2) {
                System.out.println("Too chaotic");

        int bribe = 0;
        for (int i = 0; i < q.length; i++) {
            for (int j = i + 1; j < q.length; j++) {
                if(q(i) > q(j)) {
                    q(j) = q(i) + q(j);
                    q(i) = q(j) - q(i);
                    q(j) = q(j) - q(i);

**Below is the complete code except for the method:**
public class MaximumTwoBribesAllowedForMovingForwardInQueue {

//Method that needs to be filled in
    static void minimumBribes(int() q) {


    private static final Scanner scanner = new Scanner(;

    public static void main(String() args) {
        int t = scanner.nextInt();

        for (int tItr = 0; tItr < t; tItr++) {
            int n = scanner.nextInt();

            int() q = new int(n);

            String() qItems = scanner.nextLine().split(" ");

            for (int i = 0; i < n; i++) {
                int qItem = Integer.parseInt(qItems(i));
                q(i) = qItem;

Can you please help us to recommend changes to achieve this with Java streams?

Example input:

5 1 2 3 7 8 6 4
1 2 5 3 7 8 6 4

Expected correct issue:
Too chaotic

Actual wrong issue:
Too chaotic

international travel – Can I bring cooked meat to the Netherlands?

Here are the rules for meat products:

Importation of fresh meat and meat products into the EU is subject to a veterinary certificate based on the recognition by the Directorate-General for Health and Food Safety of the competent authority of the non-EU country. This formal recognition of the reliability of the competent authority is a prerequisite for the authorization and approval of the country to export such products to the EU. Legally legitimate and duly authorized authorities in the exporting country must ensure credible controls and controls throughout the entire production chain, covering all relevant aspects of hygiene, animal health and public health

All bilateral negotiations and other relevant discussions on the import of meat and meat products must be conducted by the competent national (veterinary) authority. All other interested parties and private companies wishing to export to the EU should contact their competent authority, which in turn is in contact with the European Commission.

Importation of meat or meat products into the EU must be carried out via an EU approved border inspection post under the supervision of an official veterinarian in the EU Member State concerned.

Each shipment undergoes a systematic documentary check, identity verification and, if necessary, a physical check. The frequency of physical checks depends on the risk profile of the product and on the results of previous controls.

Shipments that are found to be non-compliant with EU legislation will either be destroyed or, under certain conditions, re-dispatched within 60 days.

Air travel – Can I bring this power bank aboard the plane?

The website you are linking to contains this FAQ

Can you take portable chargers in airplanes?

Most airlines allow lithium batteries that do not exceed 100W / h in hand luggage. The product-specific information can be found outside the Power Bank. Also contact your airline for specific information about your flight and your travel destination as there may be different regulations for airlines.

According to the same website, the specifications of this model have a 5V output, which turns from 30000 mAh to 150 Wh.

Therefore, this product may not be allowed on an aircraft. The exact answer of course depends on the airline you travel with.

Please note the IATA guidelines that are kindly provided by @jcaron.

* Before someone comes around with a hand baggage ban, that does not mean that he can not have it in checked baggage. Please note that bulk lithium batteries, regardless of their capacity, are generally never allowed in checked baggage,

Bonus tip as you are a new traveler.

Be nice to the people you will contact in due course, and no one will likely take care of this battery and let you board ๐Ÿ™‚ (It's not too far above the limit)

And whether you have the battery or not, whether you have a lot of money or not, just enjoy your travels. You are not responsible to anyone for what you have been traveling for so long.

usa – Do you need to bring a physical document for proof of residence for the Global Entry Interview?—what-do-in-need-to-bring-to-my-interview%3F ( Mirror) says:

As a rule, the following original documents are required:

(…) documents proving residence. Examples are: driver's license (if the address is current), mortgage card, rental card, utility bill, etc. This is not required for minors.

Is it necessary to bring a physical document for proof of residence for the global immigration interview or is it acceptable to submit an electronic version of it (eg.

uk – Can I bring NEW PC PARTS (still in the box) in my checked baggage?

In the UK, security knows what computer parts are and what they look like on the screens. If in doubt, you'll be asked to unpack an item so you can actually see it.

You should take these items with you in your carry-on baggage as valuables and fragile items must not be packed in your checked baggage. But you seem to have too much for your hand luggage. In this case, you have to pack some of your checked baggage and run the risk of being lost or broken.

The British side only checks to see if you can damage the plane and the people inside it, and most computer parts are not known to be dangerous. Batteries should not get into the luggage.

If you arrive at the other end, you must state that customs in South Africa appreciate and bill you for what he considers worth. It does not matter if you have packed the pieces in boxes or at home, as they judiciously judge whether they are new or almost new and recharge accordingly.

Never lie to immigration and customs officials, because they can make your life difficult, and it's a kind of lie to hide that they're new. Some people will be able to take it off, the rest will be charged for new parts, possibly with an extra charge for trying to fool you.
Since you will receive your checked baggage before you pass customs, it does not matter in which part of your baggage your computer parts are.

With a value of ยฃ 2000, I'm pretty sure customs in South Africa will charge you fees.
Only if you or your husband bring you out soon, you could get away with a "temporary import," though I'm not sure how to handle it in South Africa.

dnd 5e – Would it be possible to bring a dragon to CR27 only with official material and variants (Shadow Dragon / Dracolich, innate spells etc)?

Ancient Gold Dragons and Ancient Red Dragons have a CR of 24. This means they could know spells up to the eighth level if you had such a Dragon of the Innate Magical Dragon Variety (MM p.86). I wonder if it's possible to bring a kite to CR27 (to gain access to 9th-level spells) using only official materials and variant rules.

According to my calculations, an ancient gold dragon has a defensive CR of 25 and an offensive CR of 22 or 23, which corresponds to an average CR of 24. To achieve an average CR of 27, the easiest route would probably be the best by increasing the OCR, as there is more room for improvement. To get CR27, the OCR would have to be at least 28. The Ancient Gold Dragon gains +2 OCR as its attack bonus is exceptionally high, which means its damage should equal CR26. This averages 231-248 damage per round in the first three combat rounds.

As far as I know, making a Shadow Dragon or Dracolich does not significantly increase the damage. A Shadow Dragon's weapon is more deadly, since it kills immediately when a character drops to 0, but I do not know how to quantify it.

Is there a selection of levels 1-8 spells that could be given to a dragon to bring its OCR to 28? Or is there another way to bring a kite to CR27 that I missed?

css – Bring the Hero element to full width

I'm trying to learn a few new designs.

Consider this sample website:


* please do not do that Not My design, I show it because that's the effect I'm aiming for.

The image of the boy actually sits in the hero element and somehow the designers have managed to design the element in full width (on all devices). On my side:

Although I coded it as:

.hero {
  height: 1334px;
    Width: 1110px;
    background-image: url("wp-content/uploads/2019/09/hpimage-2.jpg");
  color: transparent;
  background: #000000;
  padding: 0px;
    background-size: contain;

The container does not reach the pages of the pages (I marked the background in yellow to highlight it). Does anyone know how I can achieve the effect that I see on on my website?

Thank you very much,
