input: Write a function to generate a 3x3 array of random integers ranging from 1 to 5 using the NumPy library. Return the generated array.
  import numpy as np
  
  assert np.array_equal(generate_random_array(), np.random.randint(1, 6, size=(3,3)))
output: def generate_random_array():
      return np.random.randint(1, 6, size=(3, 3))
