In swift. At first I add submit code and I failed in only test case 5 then I do nothing any change and jst again click submit code I passed in all test cases.

class TrieNode {
var children = Array<TrieNode?>(repeating: nil, count: 2)

func add(value: Int, index: Int) {
        let bitPos = 31 - index
  if bitPos < 0 { return }

  let power = 1 << bitPos
  let bit = (value & power) >> bitPos // Extract the bit at the current position
  let remainder = value & (power - 1) // Calculate the remainder

  if let child = children[bit] {
            child.add(value: remainder, index: index + 1)
  } else {
            children[bit] = TrieNode()
    children[bit]!.add(value: remainder, index: index + 1)
        }
}
}

struct BitTrie {
    let root = TrieNode()

func add(_ value: Int) {
        root.add(value: value, index: 0)
}

func getMaxXor(_ value: Int) -> Int {
        var current = root
  var xorValue = 0
  var remainder = value

  for i in 0..<32 {
            let bitPos = 31 - i
    let power = 1 << bitPos
    let bit = (remainder & power) >> bitPos // Extract the bit at the current position
    remainder = remainder & (power - 1) // Calculate the remainder

    if let child = current.children[bit ^ 1] {
                xorValue += power
      current = child
             } else {
                 current = current.children[bit]!
     }
   }

   return xorValue
        }
    }

// Complete the maxXor function below.
func maxXor(arr: [Int], queries: [Int]) -> [Int] {
    var maxVals = [Int]()
let trie = BitTrie()

for value in arr {
        trie.add(value)
}

for query in queries {
        maxVals.append(trie.getMaxXor(query))
}

return maxVals
}
