# Smallest Integer

# I worked on this challenge [by myself, with: ].

# 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)
  smallest = nil
  list_of_nums.each do |integer|
    if smallest == nil || integer < smallest
      smallest = integer
    end
  end
  return smallest
end
