String Palindrome
Write a function to find if the given string string is palindrome or not. Return 1 if the input string is a palindrome, else return 0.
Input specification:
Input 1: A string of characters.
Output Specification:
0 or 1 depending on whether the string is a palindrome or not.
Example 1:
Input 1: level
Output: 1
Explanation:
The reverse of string ‘level’ is ‘level’. As they are same hence the string is a palindrome.
Example 2:
Input 1: abcd
Output: 0
Explanation:
The reverse of string ‘abcd’ is ‘dcba’. As they are not the same hence the string is not a palindrome.

s=input()
s_rev=list(reversed(s)) #returns a list of the reversed string
revStr=''.join(s_rev) #joins the elements of the reversed list to a string
#print(revStr)
if s==revStr:
print('1')
else:
print('0')
