# Lines beginning with hash marks are comments.

# Homework #0 will be worth 20 points -- other
# homeworks will be worth 100 points.
# One purpose of homework #0 is to make sure 
# you can use the submit system on the Zoo.  
# You will receive no credit for this assignment
# until you successfully use the submit system to submit it.

# You will be submitting *two* files for homework #0.
# Please name them:
# hw0.py (for the Python definitions and procedures)
# response.txt (for the reading response)

# ********************************************************
# ** problem 0 ** (1 easy point) 
# replace the number 0 in this definition to
# indicate how many hours you spent doing this assignment.
# Fractions are fine, eg, 3.14159.

# ** problem 1 ** (5 points)

''' 
 Write a procedure productorsum(x, y)

which takes two integer arguments, and returns their product, 
unless the product is greater than 1000, in which case 
it returns their sum.

Examples

>>> productorsum(1,2) => 2
>>> productorsum(100,200) => 300
>>> productorsum(40,50) => 90
>>> productorsum(40,-50) => -2000

'''

# ********************************************************

def productorsum(x,y):
    pass

    # Replace the pass statement above with your procedure 


# Your procedure will
# be tested automatically, but it will
# be called only on integer arguments.

# ********************************************************
# ** problem 2 ** (4 points)

# Write a procedure food()
# that takes no arguments and
# returns a *string* indicating
# your favorite food

# Example (yours will likely be different)

# food() => "bacon"

# ********************************************************

def food():
    pass

# Replace the pass statement above this comment with your procedure.
# Note that it is named food and takes
# no arguments.  Your procedure will be
# tested automatically, and will be called
# only with no arguments.  Note the parentheses
# following food indicating a procedure
# application.

# ********************************************************
# ** problem 3 ** (10 points)

# For this problem, you are asked to find one
# article (of 2 pages or more) in
# the magazine "Communications of the ACM",
# in one of the issues: June, July, August, 
# September 2023

# See http://cacm.acm.org/
# Read the article and answer 
# the following three questions:

#   a. What did you know about the topic
#      prior to reading the article?
#   b. What did you learn from reading the
#      article?
#   c. What more would you like to know
#      about the topic?

# Your answer should be *at most* 400 words,
# saved in .txt format, and submitted as
# the file response.txt for assignment 0.
# Please include in your file 
# your name and email address
# and the title and author(s) of the article
# you are responding to.
