input: Write a python function to randomly select a number of items, but with a given algorithm.
  assert len(select_with_algorithm([1, 2, 3, 4, 5, 6, 7], 3)) == 3
  assert len(select_with_algorithm([1, 2, 3, 4, 5, 6, 7], 5)) == 5
  assert len(select_with_algorithm([1, 2, 3, 4, 5, 6, 7], 7)) == 7
output: import random
  
  def select_with_algorithm(items, n):
      return random.sample(items, n)
