# Consider an array of sheep where some sheep may be missing from their place.
# We need a function that counts the number of sheep present in the array
# (true means present).
#
# For example,
#
# [True,  True,  True,  False,
#   True,  True,  True,  True ,
#   True,  False, True,  False,
#   True,  False, False, True ,
#   True,  True,  True,  True ,
#   False, False, True,  True]
#
# The correct answer would be 17.
#
# Hint: Don't forget to check for bad values like null/undefined


def count_sheeps(arr):
    return sum([1 for element in arr if element == True])
