Problem

Implement a small utility for ValueMomentum's engineering toolkit that performs two independent integer operations: reverse the digits of a number without converting it to a string, and swap two integer values without using a third variable.

Write a function that accepts an integer number and two integers a and b. It must return a tuple containing the reversed number, the swapped value of a, and the swapped value of b.

A negative number must remain negative after reversal. Leading zeroes created by reversal are discarded naturally. For example, reversing 1200 produces 21.

Formal Specification

  • Input: three integers, number, a, and b.
  • Output: a tuple (reversed_number, new_a, new_b).
  • Reverse number using arithmetic operations such as division, remainder, and multiplication.
  • Swap a and b without declaring or using a temporary variable for the swap.
  • Do not convert number to a string.

Constraints

  • -10^9 <= number <= 10^9
  • -10^9 <= a, b <= 10^9
  • All inputs are integers
  • The number must not be converted to a string
