How do you use a stack to check if a string is a palindrome string?
If the length of the string is odd then neglect the middle character. Till the end of the string, keep popping elements from the stack and compare them with the current character i.e. string[i]. If there is a mismatch then the string is not a palindrome. If all the elements match then the string is a palindrome.
How do you implement palindromes?
Palindrome number algorithm
- Get the number to check for palindrome.
- Hold the number in temporary variable.
- Reverse the number.
- Compare the temporary number with reversed number.
- If both numbers are same, print “palindrome number”
- Else print “not palindrome number”

How to check palindrome using JavaScript?
Implementing Palindrome check in JavaScript will be a 3 step process : Read the input string as parameter. Convert the input string as array. Reverse the array and convert to string. Compare the input string and the reversed string, if same, you have a palindrome.
How to check if a number is palindrome in Java?
First, given number ( num )’s value is stored in another integer variable, originalInteger. Then, a while loop is used to loop through num until it is equal to 0. On each iteration, the last digit of num is stored in the remainder. Finally, reversedInteger and originalInteger are compared. If equal, it is a palindrome number. If not, it isn’t.
What is a palindrome algorithm?
A palindrome is a word or sentence that is the same when read backwards. In the case of sentences, spaces are ignored. This is an algorithm to detect palindromic words represented as a string of characters, in pseudocode. (Indices are one-based)
