Write a Java program to recursively determine if a given string is a palindrome. Make sure the program is done recursively. Definition of a palindrome Links to an external site.  Input Data:     Repeatedly, enter one string at a time at the keyboard         alternatively, you may set up an input data file and get the data from the file     Stop the inputting, when the user does not want to enter any additional strings Processing: Set up a method to  recursively determine if a given string is a palindrome.   Output Data:          The attached screenshot displays sample output, when a program is run based on the above problem statement:

python multiple choice  Code Example 4-1 def get_username(first, last):     s = first + "." + last     return s.lower()   def main():     first_name = input("Enter your first name: ")     last_name = input("Enter your last name: ")     username = get_username(first_name, last_name)     print("Your username is: " + username)     main()      5.       Refer to Code Example 4-1: What is the scope of the variable named s ?a.    globalb.    localc.    global in main() but local in get_username()d.    local in main() but global in get_username()

javascripts write a loop prints all three digits number in decreasing order (999 , 998 ,997,..,101,100)

In PYTHON use a Monte Carlo Simulation to write a code that gives the probability that in a classroom of x people, at least 2 will be born on the same day of the year, ignoring leap year? The number of people in the class is given by the user as variable x.   Here is the code outline that is needed to answer this question. Please use it in your answer: import mathimport random # create and initialize frequency table:ft = []k = 0while(k < 365) :  ft.append(0)  k = k+1 # Allow the user to determine class size:print("Please type in how many people are in the class: ")x= int(input()) success = 0 # Simulate:c = 0while(c < 10000) :    # Step 1:  re-initialize birthday frequency table (it must be re-initialized for each play-through (why?):  k = 0  while(k < 365) :    ft[k] = 0    k = k+1    # Step 2:  randomly get x birthdays and update frequency table:  k = 0  while(k < x):    # your code goes here ##########################             k = k+1    # Step 3: Check to see if this…
