An 'array palindrome' is an array, which, when its elements are reversed, remains the same. Write a recursive function, isPalindrome, that accepts a tuple and returns whether the tuple is a palindrome. A tuple is a palindrome if: the tuple is empty or contains one element the first and last elements of the tuple are the same, and the rest of the tuple is a palindrome

Following are the program in the Python Programming Language.

#define function

def isPalindrome (test):

#set the if condition to check tuple is empty

if (len (test) = =0):

return True

#Check the tuple contain 1 element

elif (len (test) = =1):

return True

#check the element of tuple is palindrome or not

else:

lenth=len (test)

#check first last element is equal or not

if (test[0]==test[lenth-1] and isPalindrome (test[1:lenth-1])):

#then, return true

return True

#otherwise

else:

#Return False,

return False

#define tuple type variable and initialize

test = (1,2,3,4,3,2,1)

#print and call the function

print (isPalindrome (test))

Output:

True

Explanation:

Here, we define a function "palindrome () " and pass an argument in its parameter, inside the function.

Set the if conditional statement to check the following tuple is empty or not if the tuple is empty then, it returns true. Set the elif conditional statement to check the following tuple containing one element, then it returns True. Otherwise, we set the length of the tuple in the variable "lenth". Then, set if conditional statement to check the first and the last element of the tuple is the same then, returns true. Otherwise, it return false.
