hey, i am unable to get what logic u are trying to apply to this, although some mistakes i found are:
let me just point out the mistakes

  1. question demands the answers in sorted order, so store the values in a global vector and sort it in the end and display
  2. if the vector is empty then u can print -1 that is no nodes present
  3. u don’t need to find the node, u can apply the same checks on the node’s value
  4. in ur left and right’s recursive calls u r sending i++. which sends the same value and increments for this function(the calling function), so i is never incremented in real sense and hence an infinite loop
