# Smallest Integer

# 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)

  # Your code goes here!
  smallest_integer = list_of_nums[0,1,2,3]
  list_of_nums.each do |x|
    smallest_integer = x if x < smallest_integer
  end
  return smallest_integer
end
