Problem

Implement an optimized algorithm to reverse a number and check if it is a palindrome.

Implement reverse_and_check(number), returning a tuple (reversed_number, is_palindrome). Use arithmetic operations rather than converting the number to a string. Negative numbers are not palindromes, and reversing a number must preserve its sign while removing leading zeros from the reversed result.

Constraints

  • -10^9 <= number <= 10^9
  • The input is a valid integer
  • The reversed result must be returned as an integer
