Sort by reverse domain: Write a data type Domain that represents domain names,including an appropriate compareTo() method where the natural order is in order ofthe reverse domain name. For example, the reverse domain of cs.princeton.edu isedu.princeton.cs. This is useful for web log analysis. Hint: Use s.split("\\.") tosplit the string s into tokens, delimited by dots. Write a client that reads domain names from standard input and prints the reverse domains in sorted order

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
