#2997. Minimum Number of Operations to Make Array XOR Equal to K

https://leetcode.com/problems/minimum-number-of-operations-to-make-array-xor-equal-to-k/solutions/4555750/2997-minimum-number-of-operations-to-make-array-xor-equal-to-k/?envType=daily-question&envId=2024-04-29

var minOperations = function (nums, k) {
  for (const num of nums) {
    k ^= num
  }
  return k.toString(2).replaceAll(/0/g, "").length
}

A very crammable answer that requires patience and thought
