# I worked on this challenge by myself

# smallest_integer is a method that takes an array of integers as its input
# and returns the smallest integer in the array
#
# +list_of_nums+ is an array of integers
# smallest_integer(list_of_nums) should return the smallest integer in 
# +list_of_nums+
#
# If +list_of_nums+ is empty the method should return nil

# Your Solution Below
def smallest_integer(list_of_nums)
