Write the function getComplementaryColor that:
1. Takes a string of hexColor, representing a color in hexadecimal format:
- It can consist of numbers: 0 to 9, and letters: A to F.
- It CANNOT contain the hash # symbol.
2. Returns the complementary color of the given hex color as a string:
- It must contain uppercase characters only.
- It must be preceded by the hash # symbol.
If hexColor is less than 6 characters long, pad it with zeros at the start to make up for the missing characters. Just like so:
'bc9' => '000bc9'
'' => '000000'
In case hexColor exceeds the 6 character limit or contains non-hexadecimal characters or isn't a string, the function should throw an error. For example:
getComplementaryColor('01fD08') === '#FE02F7'
getComplementaryColor('') === '#FFFFFF' // '' becomes '000000'
getComplementaryColor('a23') === '#FFF5DC' // 'a23' becomes '000a23'
getComplementaryColor('40fdEd2') // throws an error (incorrect string length)
getComplementaryColor('76ecLL') // throws an error (non-hex chars)
getComplementaryColor(293942) // throws an error (non-string type)
💡 A complementary color is a color that, when added to the original color, results in white (#FFFFFF).

Create the function countNextSmaller that:

- Returns a new array where each element represents how many numbers to the right of the current number are smaller than it.
For instance, given the array [1, 2, 0]:
- For 1, there's one element to the right (0) that is smaller, so we get 1.
- For 2, there's also one smaller element to the right (0), resulting in 1.
- For 0, there are no elements to the right, so we get 0.
- Therefore, the result for this array is [1, 1, 0].

/* Create the function getProductId that extracts the product ID from a given product page URL in your online shop.
Here's how the URLs are structured:
- The domain exampleshop.com comes first.
- Next is the product name, where words are separated by dashes (-).
- A letter p follows, marking the start of the product ID.
- The product ID itself comes next (its length can vary).
- Lastly, there's an 8-digit date (format: ddmmyyyy) indicating when the product was added, followed by .html.
The function should return the product ID as a string.
A few examples:
- exampleshop.com/fancy-coffee-cup-p-90764-12052019.html >> productID is 90764
- exampleshop.com/dry-water-just-add-water-to-get-water-p-147-24122017.html >> productID is 147
- exampleshop.com/public-toilet-proximity-radar-p-942312798-01012020.html >> productID is 942312798
Keep in mind:
- The product name might also include the letter p and digits.
- Make sure your function returns the product ID as a string.
- All provided URLs will follow the format described above. */](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:uexvzvxiyl5ntq7h46vt5vix/bafkreihvskflsm6n6qlaigwkto4riuehitib6trlw3illmwkicqvew66cy)

/*
This morning we've received a letter from the Grand Mate Hotel.
Long story short, the programmers have not changed the type of field "number of guests" in the booking form and they still receive the strings like 'Room for 4 guests, please', 'Exactly 2 people', 'Meh, I'll be alone'. Managers suffer because they are forced to process such requests manually.
Let's improve the function calculateGuests to make it look for numbers in the middle of the string guestsInput. If it is still impossible to determine the number of guests, or this number is equal to 0 - return not a number.
Requirements:
- Get only integers from string, but if there is a float number, the fraction should be omitted.
- If there are two separate integers in a string, get only the first one.
calculateGuests ('I think 5 guests') === 5
calculateGuests ('Big company of 15 dudes') === 15
calculateGuests ('5') === 5
calculateGuests ('alone') === 'not a number'
calculateGuests ('0') === 'not a number'
calculateGuests('Hello, 9.75 people') === 9
calculateGuests('There will be 7 or 9 guys') === 7
calculateGuests('hello cat walks on my keyboard ksadjfhskaj12.34kasdfhsjk') === 12
