This program will classify a string as one of the following: a palindrome, a repeated word, or “nothing special”. A word is considered repeated if it repeats only once in a string (e.g., “pizzapizza”). Some palindrome examples are: “racecar”, “aa”, and “aaa”. To determine if it is a palindrome, recommend you make use of the below method. Please make sure this program works for all cases and conditions.
/**
* This method will return a reversed version of the input string
*/
static String reverseString(String inStr)
{
String outStr = "";
if (inStr != null)
{
int startIndex = inStr.length()-1;
for (int i=startIndex; i >= 0; i--)
{
outStr = outStr + inStr.charAt(i);
}
}
return outStr;
}
A cryptogram is a coded message using alphabet substitution. For example, the letter "A" in
the cryptogram might stand for the letter “Ż." You are to write a program that allows the
program user to decipher cryptograms, like the following one. Your program should allow the
user to change one letter and display the change, then change another letter and display the
change etc.
Here is a sample cryptogram to be decoded.
String crypto.Part1 = "EKBQUDUHJ XK BCA AYGADDAMB KGENAHUEB UP"
String crypto.Part2 = "BCA ZUQDR FDEIA BCA KBEWQK PUG UOQ PEODBK."
String crypto.Part3 = "CUZALAQ PQXAMRK UOQ EODBK DXA MUB IM BCA"
String crypto.Part4 = "KBEQK FOB XM UOQKADLAK."

- Write a program that gets a string from the user and maps the capital letters into small letters, and maps the small letters into capital letters. Namely, 'A' should be changed to 'a'; 'B' should be changed to 'b'; ... 'Z' should be changed to 'z'. Similarly, 'a' should be changed to 'A'; 'b' should be changed to 'B'; etc... Your program should also change the digits into next odd number. Namely, '0' should be changed to '1'; '1' should be leaved as '1'; '2' should be changed to '3'; ... '9' should be leaved as '9'. Your program should print the final form of the altered string. Example: If the user enters: My salary is 1000 TL. The output should be: mY SALARY IS 1111 tl.arrow_forwardGiven a text string, create and return a new string of same length where all vowels have been reversed, and all other characters are kept as they were. For simplicity, in this problem only the characters aeiouAEIOU are considered vowels, and y is never a vowel. For example, given the text string "Uncle Sente lives in Russia", this method should create and return the string "Ancli Sunti levis en Resseu".Furthermore, to make this problem more interesting and the result look more palatable, this method must maintain the capitalization of vowels based on the vowel character that was originally in the position that each new vowel character is moved into. For example, "Ilkka Markus" should become "Ulkka Markis" instead of "ulkka MarkIs". Use the handy character classification methods in the Character utility class to determine whether some particular character is in upper or lower case, and convert some character to its upper or lower case version as needed. Here's the tester it must…arrow_forwardOne interesting application of computers is drawing graphs and bar charts (sometimes called histograms). Write a script that reads five numbers between 1 and 30. For each number read, output HTML5 text that displays a line containing the same number of adjacent asterisks. For ex- ample, if your program reads the number 7, it should output HTML5 text that displays *******.arrow_forward
- Write a program that gets a string from the user and reports whether or not there are repeated characters in itarrow_forward2. Write a method isPalidrome(String arg) that determines if a String is palindrome or not. Palindrome is when a String remains the same after reversing. The method should return boolean type. For example: MADAM is palindrome.arrow_forwardUsing C++ programming language. You need to create a game using strings. First generate a random letter from A to Z, this is your key and is hidden from the players. Ask player1 and player 2 to enter two strings of length 10. The player whose strings contains the key alphabet will win. If both the players have key alphabets, then the player for which it occurs earlier in the string will win. Example Run: Key: S (Not visible to user) Player1: ABDXSCJMNK; Player2: CSTUZWKMIJ Player 2 wins. HINT: string s = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; Generate a random number ‘k’ in range 0 to 25 inclusive. use Use s[k] as your random letter.arrow_forward
- Write a program which reads string and rewrite it in alphabetical order. For example, the word STRING should be written as GINRST.arrow_forwardWrite a method that accepts a String object as an argument and displays its contents backward.For instance, if the string argument is “gravity” the method should display -“ytivarg”.Demonstrate the method in a program that asks the user to input a string and then passes itto the method.arrow_forwardCreate a function that tracks how many times a phrase appears in a string. An number must be returned by the function. Never presume that a string of words can contain punctuation and only one space between words. Create the method with either a String argument or a StringBuilder object so that it can be used.arrow_forward
- Write a program that prompts the user for a sentence and display in new words. Your program should behave as follow: 1. Display a welcome message. 2. Ask the user for prompting a string with 3 words and 1 punctuation without any spaces. 3. Display the length of the string sentence. 4. Separate the words in the phrase a. Prompt user for the length of each word b. Display the complete sentence with the punctuation in the end. 5. Display a farewell message, so that the user knows that the program has terminated normally. Restrictions: No looping statements allowed (or needed). This question requires the use of the functions: length(), substr() to generate the complete sentence. Following are the sample screen shots to illustrate the expected behavior of your program. User input at the keyboard is marked with a red circle. Your program should work with any sentence with 3 words entered by the user. Assume a perfect user who will always enter correct info.

There are two ways to construct a string.1. Operation 1: You can add any character at the end of the string. It will cost you 5 points.2. Operation 2: You can copy any substring of string at the end of the string. It will cost you 6 points.The operations that you will choose to construct the string with minimum cost are:arrow_forward
