Question

Example :

ABCBA
abcba
abcba is palindrome

any programming languages are welcome

Answer 1

#python

a=input().lower()
print(a+' is palindrom.' if a==a[::-1] else a+' is not palindrom.')

Answer 2

my code ignores uppercase and spaces and punctuation. https://code.sololearn.com/WpbOkxJE38uu/?ref=app

Answer 3

This is Python, using recursion:

def palChecker(s):

def lowerS(s):
s = s.lower()
res = ''
for i in s:
if i in 'abcdefghijk\
lmnopqrstu\
vwxyz':
res = res + i
return res

def isPal(s):
if len(s) <= 1:
return True
res = (s[0] == s[-1]) and \
isPal(s[1:-1])
return res

return isPal(lowerS(s))

Answer 5

Not sure if it's exactly the same, but that's the basic implementation I learned from a John Guttag book, by the way.
