Answer 1

let n = 12321;
let remainder, reverse = 0, tempn = n;    
         
while(n > 0) {    
      remainder = n % 10; 
      reverse = (reverse * 10) + remainder;    
      n = Math.trunc(n / 10);    
}    
if (tempn === reverse)    
    console.log("Palindrome");    
else   
    console.log("Not palindrome");
