Iterative Bit Count Approach

  1. Initialize ans to 0.
  2. Start a loop that continues until the bit count of num1 is greater than ans. a. Increment ans by 1. b. Subtract num2 from num1. c. If num1 is less than ans and num2 is positive, return -1. d. If the bit count of num1 is less than or equal to ans, return ans.
  3. If the loop exits without returning, return -1.
