# Largest Integer

# I worked on this challenge [by myself].

# 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)
	
	largest = list_of_nums[0]

	if list_of_nums==[]
		return nil
	else
		list_of_nums.each do |x|
			if x>largest
				largest=x
			end
		end
		return largest
	end

end
