input: Write a python function to generate a list of 5 unique random numbers between 1 and 10.
  assert len(generate_rand_seq()) == 5
  assert all(1 <= num <= 10 for num in generate_rand_seq())
  assert len(set(generate_rand_seq())) == 5
output: import random
  
  def generate_rand_seq():
      return random.sample(range(1, 11), 5)
