input: Write a function to create a web scraper in Python that can extract hotel reviews from TripAdvisor. The function should take a URL as input, make a request to the website, parse the HTML, and extract the title and text of each review.
  assert scraper('<url1>') == [('Great stay!', 'We had an amazing time at this hotel.'), ('Not satisfied', 'The service was terrible and the rooms were dirty.')]
  assert scraper('<url2>') == [('Excellent location', 'Everything was perfect and close to everything.'), ('Disappointing', 'The staff was unfriendly and the facilities were outdated.')]
  assert scraper('<url3>') == [('Good value', 'We really enjoyed our stay and the price was reasonable.'), ('Mixed feelings', 'The breakfast was great but the room was noisy.')]
output: def scraper(url):
      import requests
      from bs4 import BeautifulSoup
      
      response = requests.get(url)
      soup = BeautifulSoup(response.text, 'html.parser')
      
      reviews = []
      for review in soup.find_all('div', class_='review-container'):
          title = review.find('div', class_='review-title').text.strip()
          text = review.find('div', class_='review-text').text.strip()
          reviews.append((title, text))
      
      return reviews
