ABOUT THE COURSE :
This course is an introduction to programming and problem solving in Python.  It does not assume any prior knowledge of programming.  Using some motivating examples, the course quickly builds up basic concepts such as conditionals, loops, functions, lists, strings and tuples.  It goes on to cover searching and sorting algorithms, dynamic programming and backtracking, as well as topics such as exception handling and using files.  As far as data structures are concerned, the course covers Python dictionaries as well as classes and objects for defining user defined datatypes such as linked lists and binary search trees.
INTENDED AUDIENCE: Students in any branch of mathematics/science/engineering, 1st year
PREREQUISITES: School level mathematics.
INDUSTRY SUPPORT: This course should be of value to any company requiring programming skills.

Assignment not submitted

All questions carry equal weightage. All Python code is assumed to be executed using Python3. You may submit as many times as you like within the deadline. Your final submission will be graded.Note:

  • If the question asks about a value of type string, remember to enclose your answer in single or double quotes.
  • If the question asks about a value of type list, remember to enclose your answer in square brackets and use commas to separate list items.

What is the value of f(8538) for the function below?

def f(x):
    d=0
    y=1
    while y <= x:
        d=d+1
        y=y*3
    return(d)

What is h(61)-h(60), given the definition of h below?

def h(n):
    s = 0
    for i in range(1,n+1):
        if n%i > 0:
           s = s+1
    return(s)
11

For what integer value n would g(87,n) return 12?

def g(m,n):
    res = 0
    while m >= n:
        res = res+1
        m = m-n
    return(res)

Consider the following function mys:

def mys(m):
    if m == 1:
        return(1)
    else:
        return(m*mys(m-1))

Which of the following is correct, assuming we always pass an integer argument to mys?
