# Largest Integer

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

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

# Your Solution Below
def largest_integer(list_of_nums)
	return nil if (list_of_nums.length==0)
	largest=list_of_nums[0]
	list_of_nums.each do |x|
		if ( x > largest)
			largest=x
		end
	end
	return largest
end
