Answer:
traversed
Explanation:
B-tree is a self balancing tree and it is a data structure which allows insertion, deletion operations.
inorder, preorder and post order, they all are traversing algorithms in the tree data structure.
inorder: first print left, then root and then right.
preorder: first print root, then left and then right.
postorder: first print left, then right and then root.
Therefore, the answer is traversed.
Answer:
def population_density(dictionary_list):
""" this function calculates the population density of a list of countries"""
total_population= 0
total_area= 0
for country in dictionary_list:
total_population += country['population']
total_area += country['area']
population_density = total_population / total_area
return population_density
Explanation:
In python, functions are defined by the "def" keyword and a dictionary is used to hold immutable data key and its value. The for loop is used to loop through the list of dictionaries and the values of the country data and extracted with bracket notation.
