This assignment is about deleting nodes from the binary search tree. You need to use given sequence to construct a binary search tree and then delete some nodes from the tree. You need to use recursive and iterative methods to write the program. So there are two codes in this assignment.
Given sequence: 6 5 8 7 1 2 4 9 10 3 11 12
Each numbers should be separated by the "space"
Sequence: 2 3 1 4 5
Step1: the sequence based on the index of the binary search tree. If there is no node at the index, then output "x". In the above example, output will be:2 1 3 x x x 4 x x x x x x x 5
Step2:You enter the index which you want to delete and then output the sequence. If there is no node at the index, then output "error" In the above example, if you enter "6", then output will be 2 1 3 x x x 5 If you enter"3", then output will be error.
