# 1
# Write a program that swaps the values in
# variables A and B.


# 2
# Write a function that takes in 5 numbers
# as input and outputs their average.


# 3
# Write a program that prompts the user
# for two numerical inputs (B and H)
# and prints out the area of a triangle
# with base B and height H.


# 4
# Do the last program again, but do it so
# that it complains if either the base
# or height is not a valid number and quits.


# 5
# Do the last program again, but do it so
# that it complains if either the length
# or width is not a valid number
# AND keeps prompting the user for a valid input till they give one


# 6
# One pound is 0.45kg.
# 1) Write a function that takes a number
#    as input and outputs its conversion
#    to kg.
# 2) Write a function that takes a number
#    as input and outputs its conversion
#    to pounds



# 7
# Write a program that does the following:
# It repeatedly prompts the user for characters
# (assume all the characters are among A, B, C, D, E)
# and prints out the letter that occurs most often.
# If there is a tie, then the alphabetically first character.
# Hint: Use a list.


# 8
# Write a function that takes 3 numbers as
# input and outputs the minimum of the 3
# numbers


# 9
# Write a function Censor that takes in a string S
# and a character C, and then replaces all occurences
# of C by "X", then returns this censored string.
# Ex: Censor("hello lil one", "l") returns
# "heXXo XiX one"



# 10
# Write a function that takes a positive
# integer n as input, and outputs the number
# of positive even integers less than n.
# (There is a way to do this and there is a better way to do this ...)


# 11
# Write a function that takes a positive
# integer n as input, and outputs the number
# of positive even integers less than n, AND
# the number of positive odd integers
# less than n.


# 12
# Write a function that takes a positive
# integer n as input, and ouputs the sum
# of the positive even integers less than n.


# 13
# Write a function that takes a positive
# integer n as input, and ouputs the sum
# of the positive odd integers less than n.


# 14
# Write a function that takes a list of
# numbers as input and returns the sum of
# the numbers in the list.



#15
# Write an Idiot Checker:
# It asks the user for a whole number between 1 and 10 inclusive
# It keeps on asking till the user enters such a number
# Once the user finally gives a proper answer it tells the user how
# how much of an idiot she/he is depending on how many tries it
# took to enter a number between 1 and 10.


#16
# Write The Dumbest Game In The World:
# It is played between two people, taking turns entering anything they like
# Whoever enters "Q" first loses.
