7. group_friends_by_food For this problem, you are given a mostly-working version of the Friend and FriendsDB classes from hw6 and hw7, and we will add new method to FriendsDB -- group_friends_by_food. group_friends_by_food returns a dictionary mapping from each of the favorite foods enjoyed by any friend to a list of the friends who enjoy that food, sorted in alphabetical order. (You can use the friends_who_love method to generate these lists.) A sample run should look like this: >>> friend1 - Friend("sarah", 165) >>> friend1.add favorite food("strawberries") >>> friend2 Friend("dweezil" 175) >>> friend2.add favorite food ("pizza") >>> friend3- Friend ("bimmy" 60) >>> friend3.add favorite food("pizza") >>> friend3.add favorite food ("strawberries"). >>> db = FriendsDB() >>> db.add friend(friend1) >>> db.add friend(friend2) >>> db.add friend(friend3) >>> db.group_friends_by_ food() {'strawberries'; ['bimmy', 'sarah'], 'pizza': ['bimmy', 'dweezil']}

Create an Ordered Doubly Linked List in C++. Remember that an ordered Linked List is one where inserts automatically place a new node so that all the nodes retain a certain order. This list should be templated where items should be in "ascending" order (i.e., if it is a list of numbers, it should be of order of least to greatest).

Assume, you have been given a dictionary where the keys present the name of the father and the value is a list of names of the sons of that person. For example A has 3 sons namely X, Y, and Z. Again X has three sons namely E, F, and G. So, A is the grandfather of E, F, and G. family = {"A" : ["X", "Y", "Z"], "B": ["M", "N"], "W" : ["A", "B"], "X" : ["E", "F", "G"]} You need to write a code which takes an input and prints the names of all his grandsons in the format shown in output samples. If he does not have any grandchildren just print “Get your sons married first! Wanna_be_grandpa!!” You can assume the input will always be a key from the dictionary. But we will check your code with a different dictionary. So do not write a code for this particular dictionary only.

given dictionaries, d1 and d2, create a new dictionary with the following property. For each entry(a,b) in d1, if a is not a key of d2 then add (a,b) to the new dictionary. For each entry (a,b) in d2, if a is not a key of d1 then add (a,b) to the new dictionary. For example, if d1 is {2:3, 8:19, 6:4, 5:12} and d2 is {2:5, 4:3, 3:9}, then the new dictionary should be {8:19, 6,4, 5:12, 4:3, 3:9}. using puthon
