Your program will generate a response based on the following rules:
if the input is of the form: your program will generate a response (randomly chosen)

yes i (do|can|will|would)
2 _____(special topics)_______ tell me more about your (special topics)…
3 why __________? why not?
4 how __________?
why do you ask?
how would an answer to that help you?
5 what __________?
what do you think?
why do you ask?
6 _____________?
i don’t know
i have no idea
i have no clue
maybe
7 ______because_______ is that the real reason?
8 i (need|think|have|want) ________ why do you (need|think|have|want) __change person_____?
9 i __________ (last word is not too) i __________ too
10 verb ________________ you verb ______________

The user name will be identified when the main function is called: (chat-with ‘user-name)
The special topics in rule 2 will include the following: family, friend(s), mom, dad, brother,
sister, girlfriend, boyfriend, children, son, daughter, child, wife, husband, home, dog,
cat, pet. If more than one special topic is found in the input, your program will pick
one randomly and ask the user about it. For example, the response to:
talk to me >>>i think it is all about family and friends
can be either:
tell me more about your friends rula
or:
tell me more about your family rula
In rule 1 and rule 8, when the chatbot repeats part of the user’s input, the pronouns must be
changed as follows:
I becomes you
am becomes are
my becomes your
your becomes my
me becomes you
you becomes me
talk to me >>>will you help me with my work?
no rula i will not help you with your work
talk to me >>>i want to understand your algorithm
why do you want to understand my algorithm?
talk to me >>>i think i am done
why do you think you are done?
talk to me >>>i have to understand you
why do you have to understand me?
For rule 10, you will use a short list of verbs that includes: tell, give, say. You can add more
verbs to the list, if you like.
