Submission instructions

1. You should submit your homework on GitHubopen in new window.
2. For this assignment you should turn in 4 separate .py files named according to the following pattern:
   hw1_q1.py, hw1_q2.py, etc.
3. Each Python file you submit should contain a header comment block as follows:

"""

No late submissions will be accepted.

REMINDER: Do not use any Python structures that we have not learned in class.

Question 01: Find the Missing Number

Acquire user input, where the user inputs a specific list. This list consists of consecutive numerical elements. However, one number is missing. Please write a program to find the missing number without using any built-in functions.

Sample Test 1:

Enter the list of numbers: 1, 2, 3, 4, 6, 7, 8
The missing number is 5.

Sample Test 2:

Enter the list of numbers: 1,2, 4, 5,6, 7,8
The missing number is 3.

Note: Here's a useful hint for the map function and a tip for solving the problem.

Map Function Usage:

• The map() function in Python applies a given function to each item of an iterable (like a list) and returns a map object (which is an iterator).

string_numbers = ['1', '2', '3', '99', '101', '131']
int_numbers = list(map(int, string_numbers))
print(int_numbers)


# ---output---
[1, 2, 3, 99, 101, 131]

Question 02: List Rotation

Prompt the user to input a specific series of numbers separated by commas. The last number represents the position to which the list will be left-rotated. All numbers before the last one are elements of the list. Do not use any built-in functions.

Sample Test:

Please enter a series of numbers separated by commas: 1, 2, 3, 4, 5, 2
List [1, 2, 3, 4, 5] After left-hand rotation [3, 4, 5, 1, 2]

Note: Here's a useful hint for the map function and a tip for solving the problem.

Map Function Usage:

• The map() function in Python applies a given function to each item of an iterable (like a list) and returns a map object (which is an iterator).

string_numbers = ['1', '2', '3', '99', '101', '131']
int_numbers = list(map(int, string_numbers))
print(int_numbers)


# ---output---
[1, 2, 3, 99, 101, 131]

Question 03: Shallow Copy Verification

Demonstrate shallow copying of a list and show how it differs from a deep copy.

Question 04: List to String Conversion

Obtain a user-input list and a specific delimiter, and concatenate the items in the user-input list into a string using the specified delimiter.

Sample Test 1:

Please enter a list of elements, separated by commas: apple, banana, orange
Please enter the delimiter you wish to use: ;
apple; banana; orange

Sample Test 2:

Please enter a list of elements, separated by commas: dog, cat, mouse
Please enter the delimiter you wish to use:  - 
dog -  cat -  mouse

Sample Test 3:

Please enter a list of elements, separated by commas: Monday, Tuesday, Wednesday, Thursday, Friday
Please enter the delimiter you wish to use: , 
Monday,  Tuesday,  Wednesday,  Thursday,  Friday

Sample Test 4:

Please enter a list of elements, separated by commas: 1, 2, 3, 4, 5
Please enter the delimiter you wish to use:  * 
1 *  2 *  3 *  4 *  5

Question 05: List Symmetry Check

Check if a list is symmetric (the same forwards and backwards).

Sample Test 1:

Enter a list of items separated by commas: 1, 2, 3, 2, 3
Is the entered list symmetric: False

Sample Test 2:

Enter a list of items separated by commas: 1,2, 3, 2, 1
Is the entered list symmetric: True

Question 06: List Element Swapping

Write a program to swap two elements in a list.

Receive user input, where the user inputs a series of numbers. The last two numbers are the indices to be swapped.

Sample Test 1:

Enter list elements followed by two positions to swap, all separated by space: 1, 2, 3, 4, 5, 1, 3
List after swapping elements: ['1', '4', '3', '2', '5']

Sample Test 2:

Enter list elements followed by two positions to swap, all separated by space: a,b, c, d, e , 0, 3
List after swapping elements: ['d', 'b', 'c', 'a', 'e']
