COMP1001 – Problem solving in IT
Due Date: 5:00pm, Friday, 2 October 2015
Assignment 3 – Text processing (40 marks)
1. [10 marks] Write a Python program that asks users for a string consisting of only the 26 English alphabets and returns the same string but
with the lowercase/uppercase inverted. For example, “AbCdEf” becomes “aBcDeF.” You may use the string methods, instead of writing
them from scratch.
2. [20 marks] Please write pseudocode for a program that receives from user his/her first name and last name, and the width and height of a text
box; and returns a printout of the name as below. Although you do not need to write a program, please write the pseudocode in a .py file
inside comments.

3. [10 marks] A coin-removing game starts with two stacks of coins. One stack has M coins and the other N, where M and N are arbitrary
positive integers. Two players take turn to remove at least one coin from a stack. The one who removes the last coin will be declared as the
winner. Your task is to write pseudocode for a winning strategy which includes choosing to be the first or second player at the beginning.
Write the pseudocode inside comments in a .py file.
