famous palindrome code example

Example 1: palindrome

//made by Kashish Vaid the great.
// Palindrome programme using for loop the easiest prgm
#include 
int main() {
    int n, rev = 0, remainder, num;
    printf("Enter an integer: ");
    scanf("%d", &n);
    num = n;

    // reversed integer is stored in rev
  for(num = n ; n!=0 ; n/=10)
{
    remainder = n%10;
    rev = rev*10 + remainder;
}
// if else shortcuts
    ( (rev == num) ? printf("%d is a palindrome.", num) : printf("%d is not a palindrome.", num) );
    return 0;
}
//made by Kashish Vaid the great.

Example 2: palindrome

function isPalindrome(sometext) {
  var replace = /[.,'!?\- \"]/g; //regex for what chars to ignore when determining if palindrome
  var text = sometext.replace(replace, '').toUpperCase(); //remove toUpperCase() for case-sensitive
  for (var i = 0; i < Math.floor(text.length/2) - 1; i++) {
    if(text.charAt(i) == text.charAt(text.length - 1 - i)) {
      continue;
    } else {
      return false;
    }
  }
  return true;
}
//EDIT: found this on https://medium.com/@jeanpan/javascript-splice-slice-split-745b1c1c05d2
//, it is much more elegant:
function isPalindrome(str) {
  return str === str.split('').reverse().join(''); 
}
//you can still add the regex and toUpperCase() if you don't want case sensitive
