- Question 4. Recursion write a Java program.A perfect number is a number whose factors, excluding the number itself, also add up to that number.For example 6 is a perfect number since its factors (other than 6 itself) 1, 2, and 3 also add up to 6 (i.e.,1+2+3 = 6). Write a program that uses a recursion to determine if an integer provided by a user byusing Scanner object is a perfect number or notplease code in python Forbidden concepts: recursion, custom classes Create a program for a used car dealership that buys and sells cars. The dealership currently has an S14, 240z, R33, and a 350z. The program must keep track of inventory. There must be options to add, remove, or print the list of cars, along with a killswitch.java Write a recursive function with two parameters: an array of ints and the number of elements in the array. The function will return the sum of all positive values in the array. Do not add any negative array elements to the sum. You can add another parameter to the function if you wish.
- This is for Java Write a recursive function that takes as a parameter a nonnegative integerand generates the following pattern of stars. If the nonnegative integer is 4,then the pattern generated is:**********Also, write a program that prompts the user to enter the number of lines inthe pattern and uses the recursive function to generate the pattern. Forexample, specifying 4 as the number of lines generates the above pattern. Java pleaseCreate a class Recursion. It will have two static methods: removeX and countSubstring and write each function recursively. Recursion class removeX The removeX function will take a String as a parameter. It will return a new String that is the same as the original String, but with all “x” characters removed. This method will be case insensitive. countSubstring The countSubstring function will take two strings as parameters and will return an integer that is the count of how many times the substring (the second parameter) appears in the first string without overlapping with itself. This method will be case insensitive. For example: countSubstring(“catwoman loves cats”, “cat”) would return 2 countSubstring(“aaa nice”, “aa”) would return 1 because “aa” only appears once without overlapping itself. Create a Main class to test and run your Recursion class.An array of integers is given. Write a recusrive function recLastname ( Use your last name ) that takes the array as argument to find the sum of the elements in the array recursively. Just the function is enough. Java code beginner please
- Create a recursive function in a file called ab_equality.py: def ab_equal(n, k, current): Print out all of the strings of a's and b's of length n so that the number of a's and b's are equal. For n = 2, there's ab and ba. For n = 3 there are no strings since they'd have to have 2 a's and 1 b, or 2 b's a 1 a so not equal. For n = 4, there will be 6 of these strings, and for n = 5, zero again. Hint: use k to track the difference between a's and b's. So for instance if your current is aaabb then k should be equal to either 1 or -1 (your choice depending). When you call the function, you should call it from your main or testing function with the length in the n parameter, 0 should be put into the k parameter, and then an empty string will be passed in for current.Fibonacci numbers are a sequence of integers, starting with 1, where the value of each number is the sum of the two previous numbers, e.g. 1, 1, 2, 3, 5, 8, etc. Write a function called fibonacci that takes a parameter, n, which contains an integer value, and have it return the nth Fibonacci number. (There are two ways to do this: one with recursion, and one without.)Without using Java environment Write a recursive function with two parameters: an array of ints and the number of elements in the array. The function will return the sum of all positive values in the array. Do not add any negative array elements to the sum. You can add another parameter to the function if you wish.
