## Non-boring sequences(分治)

We were afraid of making this question too boring, so we decided to make this question super short. A sequence is called not boring, only if there is a unique number in each successive subsequence,

## [PAT Level] 1043 IS IT A Binary Search Tree (25 points) (Judge whether or not the BST is traversed and outputs traversal traversal)

Title:

Enter a positive integer N (<=1000), and then enter the serial number of N points. If the sequence just entered is a binary search tree or its mirror image (the center is flipped 180°)
