what base case here ?? functional how it's working? int ispali(char *s, int l, int r) { return ((l == r) || (s[l] == s[r] && ispali(s, l+1, r-1))); } int main() { char str[100]; scanf("%s", str); if(ispali(str, 0, strlen(str)-1)) printf("palindrome\n"); else printf("not palindrome\n"); } it's in line of function. remember short-circuit logic in evaluating expressions. or can changed to if (l == r) return true; else return (s[l] == s[r] && ispali(s, l+1, r-1)); of course, can apply short-circuit else part: else if s[l] == s[r] return ispali(s, l+1, r-1); else return false;
