Modeling Data Petroleum imports / (in billions of dollars) for the years 1980 through 1994 are given in the table, where $t$ is the time in years, with $t=0$ corresponding to 1980 . (Source: "Highlights of U.S. Export and Import Trade" and uhe U.S. Bureau of Census)

$$\begin{array}{|c|c|c|c|c|c|} \hline \boldsymbol{t} & 0 & 1 & 2 & 3 & 4 \\ \hline \boldsymbol{I} & 77.6 & 75.6 & 59.4 & 52.3 & 55.9 \\ \hline \end{array}$$

$$\begin{array}{|l|c|c|c|c|c|} \hline \boldsymbol{t} & 5 & 6 & 7 & 8 & 9 \\ \hline \boldsymbol{I} & 49.6 & 34.1 & 41.5 & 38.8 & 49.1 \\ \hline \end{array}$$

$$\begin{array}{|c|c|c|c|c|c|} \hline t & 10 & 11 & 12 & 13 & 14 \\ \hline \boldsymbol{I} & 60.5 & 50.1 & 50.4 & 49.7 & 49.6 \\ \hline \end{array}$$

For the years given in the table, when does the model indicate that the cost of petroleum imports is at a minimum?

Using an experiment, analyze the run time of functions dup1(), dup2(), dup3(), and dup4(). You should test each function on 10 lists of size 2000, 4000, 6000, and 8000 obtained from:

import random
def buildInput(n):
    'returns a list of n random integers in range [0, n**2)'
    res = []
    for i in range(n):
        res.append(random.choice(range(n**2)))
   return res

Note that the list returned by this function is obtained by repeatedly choosing n numbers in the range from 0 to n$^2$ - 1 and may or may not contain duplicates. When done, comment on the results.

Use the functions in RandomCharacter to print 100 uppercase letters and then 100 single digits, printing ten per line.

RandomCharacter.py
1   from random import randint # import randint
2
3   # Generate a random character between ch1 and ch2
4   def getRandomCharacter(ch1, ch2):
5       return chr(randint(ord(ch1), ord(ch2)))
6
7   # Generate a random lowercase letter
8   def getRandomLowerCaseLetter():
9       return getRandomCharacter('a', 'z')
10
11  # Generate a random uppercase letter
12  def getRandomUpperCaseLetter():
13      return getRandomCharacter('A', 'Z')
14
15  # Generate a random digit character
16  def getRandomDigitCharacter():
17      return getRandomCharacter('0', '9')
18
19  # Generate a random character
20  def getRandomASCIICharacter():
21      return chr(randint(0, 127))
