input: Write a function to visualize the top 5 most popular programming languages using Matplotlib. The function should accept two lists as input: one for the names of the programming languages and the other for their corresponding popularity percentages, and it should display a bar chart with a title and axis labels.
  assert popular_languages(["Python", "Java", "C++", "Javascript", "C#"], [45, 25, 15, 10, 5])
  assert popular_languages(["Java", "Python", "C++", "Javascript", "C#"], [30, 35, 12, 13, 10])
output: def popular_languages(languages, percentages):
      import matplotlib.pyplot as plt
      plt.bar(languages, percentages)
      plt.title('Top 5 Most Popular Programming Languages')
      plt.xlabel('Programming Languages')
      plt.ylabel('Popularity Percentage')
      plt.show()
