Programming Challenges 947 4. Recursive Array Sum Write a function that accepts two arguments,, an array of integers, and a number indicating the number of elements in the array. The function should recursively calculate the sum of all the numbers in the array. Demonstrate the use of the function in a program that asks the user to enter an array of numbers and prints its sum. 5. Recursive Multiplication Write a recursive function that accepts two arguments into the parameters x and y. The function should return the value of x times y. Remember, multiplication can be performed as repeated addition: VideoNote Solving the Recursive Multiplication 7 * 4 = 4 + 4 + 4 + 4 + 4 + 4 + 4 Problem %3D 6. Recursive Member Test Write a recursive Boolean function named isMember. The function should accept three parameters: an array of integers, an integer indicating the number of elements in the array, and an integer value to be searched for. The function should return true if the value is found in the array or false if the value is not found. Demonstrate the use of the function in a program that asks the user to enter an array of numbers and a value to be searched for. 7. String Reverser Write a recursive function that accepts a string as its argument and prints the string in reverse order. Demonstrate the function in a driver program. 8. Palindrome Testing A palindrome is a string such as “madam", "radar", "dad", and “I", that reads the same forwards and backwards. The empty string is regarded as a palindrome. Write a
