Problem 3 (Palindrome)

Write a function called ispalindrome(string) that takes a string (with spaces) as argument and returns True if that string (ignoring spaces) is a palindrome. A palindrome is a word or phrase that spells the same thing forwards as backwards (ignoring spaces). Your program should use a recursive process to determine the result, by comparing the first and last letters of the string, and if necessary,

calling ispalindrome() on the rest of the string.

Sample run:
print(ispalindrome('never odd or even')) → True print(ispalindrome('is this it?')) → False

Answer 1

Code

# method to check given string is
# palindrome or not
def isPalindrome(string):
    # splitting string to words list
    string=string.split()
    # making string with all words without spaces
    string=''.join(string)
    # Getting length of the string
    length=len(string)
  
    # loop to check whether the give string is
    # palindrome or not
    # returning false if any character is not equal with
    # opposite index character
    for i in range(0,length):
        # if character not equal then return false
        if(string[i]!=string[length-i-1]):
            return False
    # return true if condition satisfies
    return True

print(isPalindrome("never odd or even"))
print(isPalindrome("is this it?"))
