Logic: Palindrome: A number is palindrome if it is equal to its reverse. Enter the number n Example 1: n=345 Reverse=543 Number is not equal to its reverse. So it is not palindrome Example 2: n=121 Reverse=121 Number is equal to its reverse. So it is palindrome Algorithm Enter the number as n Copy the …
