A palindrome is a string that reads the same forwards or backwards; for example dad, mom, deed are palindromes (i.e., reversing a palindrome produces the same string). Use C++ Programing language Write a recursive, boolean-valued function, isPalindrome that takes a string as a parameter and returns whether the string is a palindrome. A string, s, is a palindrome if: s is the empty string or s consists of a single letter (which reads the same back or forward), or the first and last characters of s are the same, and the rest of the string (i.e., the second through next-to-last characters) form a palindrome. Write a test program that reads a string from the standard input device and outputs whether the input string is a palindrome or not.

c++ A palindrome is a string that reads the same both forward and backward. For example, the string "madam" is a palindrome. Write a program that uses a recursive function to check whether a string is a palindrome. Your program must contain a value-returning recursive function that returns true if the string is a palindrome and false otherwise. Do not use any global variables; use the appropriate parameter.
A palindrome is any word, phrase, or sentence that reads the same forward and backward. Here are some well-known palindromes:Able was I, ere I saw ElbaA man, a plan, a canal, PanamaDesserts, I stressedKayakWrite a bool function that uses recursion to determine if a string argument is a palindrome. The function should return true if the argument reads the same forward andbackward. Demonstrate the function in a program.
In C++ Write a recursive function that displays a string reversely on the console using the following header:void reverseDisplay(const string& s) For example, reverseDisplay("abcd") displays dcba. Write a test programthat prompts the user to enter a string and displays its reversal.
Write a c++ recursive function that takes two integers n and k, and prints all binary strings that contains k number of ones and n is the total number of digits. Example, if n = 3 and k = 2, the following strings will be printed: 011, 101, 110 Need complete code and output screenshot
In C programing Write a recursive function that returns the product of the digits of its integer input parameter, n. You may assume that n is non-negative. For example, productDigits(243) should return 24, since 2 x 4 x 3 = 24.int productDigits (int n) {

Given two strings, this function returns true if the two strings are identical, but are in reverse order. Otherwise it returns false. For example, if the inputs are "tac" and "cat", then the function should return true. Examples: isReverse("tac", "cat") -> true Your Answer: 1 public boolean isReverse(String s1, String s2) { 2. if > 3. 4. else if > return true; return false; 5. 6. else { String s1first = String s2last return s1first.equals (s2last) && 51. substring(0, 1); s2, substring(s2.length() 1); 7. 8. 6. isReverse(s1.substring(1), s2.substring(0, s2.length() 1)); { 12} 1:11AM 50°F Clear 12/4/2021
3. A palindrome is a sentence that contains the same sequence of letters read-ing it either forwards or backwards. A classic example is "Able was I, ere I saw Elba." Write a recursive function that detects whether a string is a palindrome. The basic idea is to check that the first and last letters of the string are the same letter; if they are, then the entire string is a palindrome if everything between those letters is a palindrome. There are a couple of special cases to check for. If either the first or last character of the string is not a letter, you can check to see if the rest of the string is a palindrome with that character removed. Also, when you compare letters, make sure that you do it in a case-insensitive way. Use your function in a program that prompts a user for a phrase and then tells whether or not it is a palindrome. Here's another classic for testing: "A man, a plan, a canal, Panama!"

Write a recursive function to print all the permutations of a string. For example, for the string abc, the printout is:abcacbbacbcacabcba(Hint: Define the following two functions. The second function is a helper function.def displayPermuation(s):def displayPermuationHelper(s1, s2): The first function simply invokes displayPermuation(" ", s). The secondfunction uses a loop to move a character from s2 to s1 and recursively invokes t with a new s1 and s2. The base case is that s2 is empty and prints s1 to the console.)Write a test program that prompts the user to enter a string and displays all its permutations.
Help me please: A palindrome is a string that reads the same both forward and backward. For example, the string madam is a palindrome. Write a program that uses a recursive function to check whether a string is a palindrome. Prompt the user for a string. If the string is a palindrome output a message in the following format: madam is a palindrome else Hello is not a palindrome Your program must contain a value-returning recursive function that returns true if the string is a palindrome and false otherwise. Do not use any global variables; use the appropriate parameters.

write c++ program Write a function, isPalindrome, that returns true if a string is a palindrome and false otherwise. A string is a palindrome if it reads forward and backward in the same way. For example, the strings "madamimadam", "5", "434", and "789656987" are all palindromes. The prototype of the function is as follows: bool isPalindrome(string str);
