X275: Recursion Programming Exercise: Check Palindrome
X275: Recursion Programming Exercise: Check
Palindrome
Write a recursive function named checkPalindrome that takes a string as input, and returns true if the string is a
palindrome and false if it is not a palindrome. A string is a palindrome if it reads the same forwards or backwards.
Recall that str.charAt(a) will return the character at position a in str. str.substring(a) will return the substring of
str from position a to the end of str,while str.substring(a, b) will return the substring of str starting at position
a and continuing to (but not including) the character at position b.
Examples:
checkPalindrome ("madam") -> true
Your Answer:
1 public boolean checkPalindrome (String s) {

Microfost Visual C# 7th edition programming exercise 6-10. I need help, please.
This problem relies on the generation of a random number. You can create a random number that is at least min but less than max using the following statements:
Random ranNumberGenerator = new Random();int randomNumber;randomNumber = ranNumberGenerator.Next(min, max);
Create a game similar to Hangman named GuessAWord in which a player guesses letters to try to replicate a hidden word. Store at least eight words in an array, and randomly select one to be the hidden word.
Initially, display the hidden word using asterisks to represent each letter. Allow the user to guess letters to replace the asterisks in the hidden word until the user completes the entire word.
If the user guesses a letter that is not in the hidden word, display an appropriate message.
If the user guesses a letter that appears multiple times in the hidden word, make sure that each correct letter is placed.
Figure 6-27 shows a typical game…
