Is it a palindrome? P50497
Write a function that tells if s is a palindrome or not. Remember that a word is a palindrome if it reads the same from left to right than from right to left. In this exercise, s can be rather large; this is why it is passed by reference.
In order to compare the efficiency of your solution against the efficiency of the solution of the Judge, start checking s from its ends.
Interface
| C++ | bool is_palindrome(const string& s); |
| C | int is_palindrome(const char s[], int ssize); |
| Java | public static boolean isPalindrome(String s); |
| Python | is_palindrome(s) # returns bool |
is_palindrome(s: str) -> bool |
Observation You only need to submit the required procedure; your main program will be ignored.
