Kuidas Dartis saab kontrollida, kas string loeb ühepoolselt ja teispoolselt sama?

In Dart, you can check if a string is a palindrome (reads the same from left to right and right to left) in several ways:
- Compare the string with its reversed copy:
bool isPalindrome(String s) {
String reversed = s.split('').reversed.join('');
return s == reversed;
}
- Use two pointers — one from the start, the other from the end, and compare characters alternately:
bool isPalindrome(String s) {
int left = 0;
int right = s.length - 1;
while (left < right) {
if (s[left] != s[right]) return false;
left++;
right--;
}
return true;
}
Both methods are effective for checking if a string is a palindrome.
