foreach char in string
push on to stack
create new string
foreach char in string
pop off and add to end of new string
if new string equals old string
palindrome
else not palindrome
//when you pop off the stack, the characters come off in reverse order, thus you have reversed the original string

palindrome in every language means same. it means on reversing a number or string, if we get the same number or string as the case may be ,then the number or string is called palindrome. eg: 1221,111,252 or LIRIL,MADAM etc .
Reverse the string and compare it to the original. If they match, then it is a palindrome.
Yes, you can use regex to determine if a given string is a palindrome by reversing the string and then comparing it to the original string using regex.

One efficient way to find the longest palindrome subsequence in Java is by using dynamic programming. This involves creating a 2D array to store the lengths of palindrome subsequences for different substrings of the input string. By iterating through the string and filling in the array based on the palindrome properties, you can determine the longest palindrome subsequence.

To check if a string is a palindrome, point to each end of the string and work inwards towards the middle. If the characters pointed at differ, the string is not a palindrome. When the pointers meet or cross each other, the string is a palindrome. Note that the string cannot contain whitespace or punctuation and comparisons must not be case-sensitive.
A string palindrome is some words that put together form a sentence. An example is "A man, a plan, a canal - Panama".

You could use a function like this:function isPalindrome($string) {$string = strtolower($string);return (strrev($string) == $string) ? true : false;}and then to check a palindrome call an if statement like so:if(isPalindrome($test)) {echo $test.' is a palindrome';}else {echo $test.' is not a palindrome';}
If you mean the number 1,111 or simply 1111, this is a palindrome. A palindrome is a string or number that is spelled or written the same way forward and backward.
