Behavioral

# Statement
Create a binary tree from two integer arrays, `p_order` and `i_order`, where `p_order` represents a preorder traversal of a binary tree, and `i_order` represents an inorder traversal of the same tree.

**Constraints:**

* $1 \leq$ `p_order.length`, `i_order.length` $\leq1000$
* `i_order.length` $==$ `p_order.length`
* $-1000 \leq$ `p_order[i]`, `i_order[i]` $\leq 1000$
* `p_order` and `i_order` consist of unique values.
* Each value of `i_order` also appears in `p_order` and vice versa.
