2429. Minimize XOR

Leetcode Solutions

Bit Manipulation and Greedy Approach

  1. Count the number of set bits in num2 and store it in a variable setBitsNum2.
  2. Initialize x to 0.
  3. Iterate over the bits of num1 from MSB to LSB: a. If the current bit in num1 is set and setBitsNum2 is not zero, set the corresponding bit in x and decrement setBitsNum2.
  4. If setBitsNum2 is still greater than zero after step 3, it means we need to set more bits in x: a. Iterate over the bits of x from LSB to MSB. b. For each bit that is not set in x, set it and decrement setBitsNum2 until it reaches zero.
  5. Return x as the result.
