The problem provides you with modified preorder input. You take an integer as input for data. Then you ask for the existence of its left child. If you get “true” , the left child exists and you take input for left child . Otherwise if you get “false” , the child doesn’t exist and then you simply move on with the right child just like PreOrder function. Refer to my input function for further clarification and let me know if you have any further doubts regarding it.
