Question
Chapter 9.4, Problem 9.18CP
Program Plan Intro
String class:
- The “String” class provides a number of methods that examines for a string inside of a string.
- The term “substring” refers to a string that denotes another string’s part.
- The “startsWith” method would determine whether calling string of object begins with a specific substring.
- The method returns “true” if string begins with specified substring, it returns “false” otherwise.
- The “endsWith” method would determine whether calling string would end with a specified substring.
- The method returns “true” if string ends with specified substring, it returns “false” otherwise.
- The “regionMatches” method would determine whether specified regions for two strings match.
- The first argument of this method can be “true” or “false” that indicates whether a case-insensitive comparison could be performed.
StringBuilder class:
- The “StringBuilder” class is same as “String” class except that contents of “StringBuilder” objects could be changed.
- It provides several methods that “String” class does not have.
- The “append” method accepts an argument that might be a primitive data type.
- It appends a string representation to contents of calling object.
- The “insert” method accepts two arguments, an integer that specifies position in string of calling object as well as value to be inserted.
- The “replace” method replaces the occurrences of one character with another character.
- The “toString” method converts a “StringBuilder” object in to a regular string.

Java code
Tom loves strings very much but he loves palindromic strings even more. Today he found an old rope
in his garage. The string is so old that some of its characters have disappeared and cannot be
identified now. Blurred letters in the character unit are represented by '.' and the other letters are
Latin letters of the word ['a' - 'z'].
The palindrome tom has decided to build a very small palindrome according to the dictionary by
filling in each diminished letter ('.') In Latin with a lowercase letter. Can you help her finish the job
using C++ programming language?

Spilitology
Yosef is a peculiar fellow. He introduced the idea to study a string by splitting it into two, and he called it Splitology. Why split a string? We do not know. Didn’t we say that Yosef is a weird one? Yosef is interested in one particular type of string, a palindrome. A palindrome is a string that is the same for both forwards and backwards. Example of palindrome strings are “ada”, “taat”, and “radar”. On the other hand, string such as “taman” is not a palindrome; notice that “taman” becomes “namat” if read backwardsand it’s not the same as “taman”. As the idea of Splitology is still new, Yosef is investigating whether a string can be split into two non-empty strings such that each string is a palindrome. For example, the string “malamini” can be split into “malam” and “ini” while both of them are palindrome. Another example is “ababab”. It can be split into “aba” and “bab”, and both of them are palindrome. Note that “ababab” can also be split into…

- Target The aim of this work is to use control structures and loops. Read carefully the problem and understand what needs to be done. Read your description is given and when you understand how it works, then start designing its solution and its implementation on the computer applying the syntax and semantics of the language Java programming. Write a LongestDupSubstring.java program that accepts a string as input and compute and print the longest sub-string displayed in two times without overlap (see 5th example for overlap). If there are more from one of such sub-strings, the program displays the first one it finds as well the number of characters in the substring. If there is no substring that appears 2 times, then the program will not print anything.

- Do Fast.arrow_forwardA 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.
