- 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.c++ A palindrome is a string that reads the same both forward and backward. For example, the string "madam" is a palindrome.

- Write a recursive function that parses a hex number as a string into a decimal integer. The function header is as follows:def hexToDecimal(hexString):Write a test program that prompts the user to enter a hex string and displays its decimal equivalent.Write a recursive function to return the number of uppercase letters in a string using the following function headers:def countUppercase(s):def countUppercaseHelper(s, high): Write a test program that prompts the user to enter a string and displays the number of uppercase letters in the string.Write a recursive function that converts a decimal number into a binary number as a string. The function header is as follows:def decimalToBinary(value): Write a test program that prompts the user to enter a decimal number and displays its binary equivalent.
- 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.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 that displays a string reversely on the console using the following header: def reverseDisplay(value):For example, reverseDisplay("abcd") displays dcba. Write a test programthat prompts the user to enter a string and displays its reversal.

Write a test program that prompts the user to enter a string and displays its reversal.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) {Write a recursive function that finds the number of occurrences of a specified letter in a string using the following function header. def count(s, a):For example, count("Welcome", 'e') returns 2. Write a test program thatprompts the user to enter a string and a character, and displays the number of occurrences for the character in the string.
