Palindrome

Return 1 if a C-string reads the same in both directions, otherwise 0 — in C there's no bool by default, so we use the integers 1 and 0. Compare characters from the two ends moving inward.

Complete int is_palindrome(const char *s) to return 1 if s reads the same forwards and backwards, otherwise 0.

/* Return 1 if s reads the same both ways, else 0. Do not write main(). */
int is_palindrome(const char *s) {
    return 0;   /* change this */
}
