The below displays ice-creams with its associated flavours. This we would display using <UL>

Here <UL> tag is used to create un ordered list and one another <UL> tag inside <LI> created nested list which is the actual requirement. Like this we can created nested unordered lists and you can nest upto 4 levels and increasing the number of levels further may reduce clarity.

Answer:
def is_dual( array):
if len(array) % 2 == 0:
count = 0
for i in range(0, len(array)//2, 2):
if array[i] + array[i+1] == array[0] + array[1]:
count += 1
if count == len(array)//2:
return True
else:
return False
Explanation:
The python program defines a function called is_dual that accepts an array parameter and check if the array is dual. If it meets the condition, the function returns true but returns false when the array is not dual.
