Chapter 6, Problem 13PE
Program Plan Intro
Program plan:
- The function named “toNumbers()” is defined and inside the “toNumbers()”,
- Initialize the for loop that ranges till the length of the array
- The variable “strList[]” stores the integer value of the string values in the array.
- Return the value stored in the variable “strList”
- Initialize the for loop that ranges till the length of the array
- In the “test()” function,
- Declare an array variable and initialize it with an array.
- Call the method named “toNumbers()” to get the integer value of the string.
- Print the output value stored in the variable “z”.
- Call the function “test()”.

3. String
(a)
Write a Python function that accepts a string s and an integer n with a single
digit (i.e., 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9) as its arguments, and returns a new string that
replaces every digit n found in s by a new digit that equals to (n + 1) %10. The function
returns an empty string if n is not a single digit integer or is negative.

(b)
Write a Python function that accepts a string as the argument, moves the first
3 characters of the string to the end, and prints it out. If the length of the string is less than
3, your function should print an error message.

Write a recursive function named get_palindromes (words) that takes a list of words as a parameter. The function should return a list of all the palindromes in the list. The function returns an
empty list if there are no palindromes in the list or if the list is empty. For example, if the list is ["racecar", "hello", "noon", "goodbye"], the function should return ["racecar", "noon"].
A palindrome is a word that is spelled the same forwards and backwards.
Note: The get_palindromes() function has to be recursive; you are not allowed to use loops to solve this problem.
For example:
Test
words = ["racecar", "hello", "noon", "goodbye", "test", 'aibohphobia'] ['racecar', 'noon', 'aibohphobia']
print (get_palindromes (words))
print (get_palindromes ([]))
print (get_palindromes (['this', 'is', 'test']))
Answer: (penalty regime: 0, 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 %)

- Ex1: a) Write a function for the user to enter a positive integer n with a value between 10 and 1000. If entered correctly, the function generates a list containing n random values that do not overlap between 1 and 5000 and the function returns the newly created list. Conversely, if entered incorrectly, the program will ask to re-enter until it is correct. Cases where n is considered incorrect:(i)- If the user enters a non-integer data type (like string, float, bool, ...)The program will display the error message 'Must enter a positive integer. Requires re-entry'.(ii)- If the input value is of the correct integer data type but the value is not in the range10 to 1000, the program gives the error 'Only values between 10 and 1000. Re-enter required'.Installation requirements: must use the try ... except statement to handle possible exceptionsin the program. b) Write a function that lists the amicable numbers in the list just created in a) (If there are no amicable numbers in the list,…arrow_forwardReturn Growing NumList This function will be given a single number, it should return a list of strings of numbers.

- Exercise, maxCylinderVolume F# system function such as min or methods in the list module such as List.map are not allowed Write a function maxCylinderVolume that takes a list of floating-point tuples that represent dimensions of a cylinder and returns the volume of the cylinder that has the largest volume. Each tuple has two floating point values that are both greater than zero. The first value is the radius r and the second value is the height h. The volume of the cylinder is computed using ??2h. The value π is represented in F# with System.Math.PI. If the list is empty, return 0.0.
