# 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)
  minimum = nil
  list_of_nums.each do |num|
  	num = num.to_i
  	if minimum == nil	
  		minimum = num
  	elsif minimum.to_i > num
  		minimum = num
  	end
  end
  return minimum
end
