Program Plan Intro

Program to display the integer value of the string

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”
  • 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. COMP132 Assignment #2 replace_string("He330", 3)-> "He440" "He331" replace_string("He330",0)-> replace_string("He330",-4) replace_string("He330", -> 12)-> 11 11 11 11 (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. move_string ("Hello") ->loHel move_string ("Hi, My name is Mark.") -> My name is Mark. Hi, move_string ("Hi")->Invalid String
Question > Not complete Marked out of 1.50 Flag question Previous page 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 %) Result Precheck Check [] [] Next page
String Pair   // Problem Description   // One person hands over the list of digits to Mr. String, But Mr. String understands only strings. Within strings also he understands only vowels. Mr. String needs your help to find the total number of pairs which add up to a certain digit D.       // The rules to calculate digit D are as follow       // Take all digits and convert them into their textual representation       // Next, sum up the number of vowels i.e. {a, e, i, o, u} from all textual representation       // This sum is digit D       // Now, once digit D is known find out all unordered pairs of numbers in input whose sum is equal to D. Refer example section for better understanding.       // Constraints   // 1 <= N <= 100       // 1 <= value of each element in second line of input <= 100       // Number 100, if and when it appears in input should be converted to textual representation as hundred and not as one hundred. Hence number…
