Question.Use Python Code Correctly to solve this problem.A phrase is a palindrome if, after converting all uppercase letters into lowercase letters andremoving all non-alphanumeric characters, it reads the same forward and backward. Alphanumericcharacters include letters and numbers.Given a string s, return true if it is a palindrome, or false otherwise.Example 1:Input: s= "A man, a plan, a canal: Panama "Output: true Explanation: "amanaplanacanalpanama"is a palindrome.Example 2:Input: s = "race a car"Output: falseExplanation: "raceacar" is not a palindrome.Example 3:Input: s = " "Output: trueExplanation: s is an empty string after removing non-alphanumeric characters.Since an empty string reads the same forward and backward, it is a palindrome.Constraints:1 <= s.length <= 2 * 105s consists only of printable ASCII characters.11 11

Q_4.*. A phrase is a palindrome if, after converting all uppercase letters into lowercase letters and removing all non-alphanumeric characters, it reads the same forward and backward. Alphanumeric characters include letters and numbers. Given a string s, return true if it is a palindrome, or false otherwise. Example 1: Input: s = "A man, a plan, a canal: Panama" Output: true Explanation: "amanaplanacanalpanama" is a palindrome. Example 2: Input: s = "race a car" Output: false Explanation: "raceacar" is not a palindrome..
3. Write a program that transforms numbers 1, 2, 3,..., 12 into the corresponding month names January, February, March, ..., December. Hint: Make a very long string "January February March ...", in which you add spaces such that each month name has the same length. Then use substring to extract the month you want.
Given a string that may contain Azerbaijani letters, change them to the closest subsitude in English letters. (ü->u, ö->o, ğ->gh, ı->i, ə->a, ç->ch, ş->sh). Example: Üzüm => Uzum WRITE IN PYTHON SHOW CODES AND OUTPUT PLEASE
java: Run length coding is a method to represent a string in a more compact manner. Each character that occurs more than 2 times in a row is represented by the character and a number following it. Two examples are: "abba" → "abba""abcccbbbba" → "abc3b4a"Write a function that calculates how many characters the encoded string is shorter than the original.
1. a Write a regular expression for the set of binary strings where each string has at least one pair of consecutive zeros. b. write the regular expression for the following, where sigma = (a,b): i. string of length at least 2 ii. string of length at most 2 iii. all string starting with a and ending with b iv. Even length Strings
Determine whether a string is a palindrome A palindrome is a string of characters that reads the same from right to left as it does from left to right, regardless of punctuation and spaces. Some famous English palindromes include the following “Madam, I’m Adam”, and “Never odd or even”. Of course, a simpler example would be the world “radar”.The specifications for this assignment are: Write and test a non-recursive solution in Java that determines whether a string is a palindrome •Your program should consist of at least two methods: (1) the main method (2) the method which performs the task of determining whether the specified string is a palindrome. You should name this method isPalindrome. You should name the class that contains your “main” method and the isPalindrome method FindPalindrome. •You must use a Stack and a Queue in your solution:Make sure to Write your own Stack and Queue based on the Vector in the Java API and use those in your solution. You should name those classes…
A string is a palindrome if it reads the same from front to back as it does from back to front (e.g. "kayak", "rotator" and "noon" are palindromes). When determining whether an alphanumeric string is a palindrome, we often ignore spaces, punctuation and case in the string (e.g. "A man, a plan, a canal --Panama!" is also considered a palindrome). Write a complete C program to read a string, echo it to the screen, determine whether it is a palindrome, and write a message indicating whether it is or isn't. Your main function should prompt for the string, read the string, print it, call the clean function (to remove all spaces, punctuation, and turn uppercase letters into lowercase letters), print the new string, then call the reverse function (to place the characters into reverse order) and print the new string resulting. In the final step, you will compare the result of the reverse function with the original string and print a message if the string is a palindrome or not. The clean…
Please &-. Write a Java program to check if a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward, ignoring spaces, punctuation, and capitalization. For example, "racecar" and "Madam" are palindromes, while "hello" and "Java" are not. Your program should take a string as input and return true if it's a palindrome, and false otherwise. Ik.?
5. Given a string s, find the length of the longest substring without repeating characters. Example 1: Input: s = "abcabcbb" Output: 3 Explanation: The answer is "abc", with the length of 3. Example 2: Input: s = "bbbbb" Output: 1 Explanation: The answer is "b", with the length of 1..
In Python, with use of function and input parsing/ Make a method is_anagram_of(a,b) that tests if a is an anagram of b. A string a is an anagram of a string b, if it uses exactly the same letters, but the order can be different. Spaces are ignored, as well as capitalization. Examples of anagrams: "eleven plus two" - "twelve plus one" "William Shakespeare" - "I am a weakish speller" "Tom Marvolo Riddle" - "I am Lord Voldemort" "Anagrams" - "Ars manga" "television ads" - "enslave idiots" Counter examples: "bla" - "aalb" "cat" - "tact" Hint: Make a dictionary that holds how often a letter occurs in a word.
Take input a string s from the user and print the number of characters less than 's' in the string. Given: String may contain any character. In Java language.
Given a string on one line and an integer number on a second line, add a copy of the last number of characters of the string to the string's end. Then, output the result. Ex: If the input is: Fuzzy bear 4 the output is: Fuzzy bearbear Note: Using a pre-defined string function, the solution can be just one line of code. #include <iostream>#include <string>using namespace std; int main() { string strVar; int substrLen; getline(cin, strVar); cin >> substrLen; /* Your code goes here */ cout << strVar << endl; return 0;}
