Exercise 1: A palindrome is a string of characters that reads the same for- wards as backwards. For example, the following are both palindromes: 1457887541   madam Write a program that prompts the user to input a string of a size 50 characters or less. Your program should then determine whether or not the e

Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string and an integer as input, and outputs a sentence using the input values as shown in the example below. The program repeats until the input string is quit and disregards the integer input that follows. Ex: If the input is: apples 5 shoes 2 quit 0 the output is: Eating 5 apples a day keeps the doctor away. Eating 2 shoes a day keeps the doctor away.

Aim: Read a string, S and print its integer value. If S cannot be converted to   an integer, print Bad String.       '''       # getting the input   S = input().strip()   try:   # if it's possible to convert the entered string into an integer then this block will execute   print(int(S))   except:   # if it's not possible, then this block will be executed   print('Bad String')       '''       COMPLEXITY:       Time Complexity -> O(1)   Space Complexity -> O(1)       Sample Input 1:   3   Sample Output 1:   3   Sample Input 2:   SB   Sample Output 2:   Bad String       Explaination:   '3' as a string can be converted into the integer 3, whereas SB can't be   converted to an integer hence the 'except' block is executed and 'Bad String'   is printed.

Task 3. Remove white spaces and special symbols Program asks user to input a string to remove white spaces and special symbols (dashes, commas and dots). User inputs a string (with several words) and program prints out the input string without white spaces and special symbols. You may use Scan objects and loops. Example: Input a string to remove special symbols: hey, - i like may. Result: heyilikemay
