    I really don't understand what it wanted me to do. it doesn't complicate, but i have to research to understand that what it really wanted me to do

      // Write your code here
    arr := make([][]int32, n) 
    result:= make([]int32, 0)
    lastAnswer := int32(0);
    for _, query := range queries {
      qType := query[0]
      x := query[1]
      y := query[2]
      idx := (x ^ lastAnswer) % n
    if qType == 1 {
      arr[idx] = append(arr[idx], y)
    } else if qType == 2 {
      lastAnswer = arr[idx][y % int32(len(arr[idx]))]
      result = append(result, lastAnswer)
      }
    }
    return result
