Learn essential coding patterns to answer problems and prepare for tech companies' interviews.

Ace the Java Coding Interview

This module teaches us the underlying patterns behind common coding interview questions. By learning these essential patterns, we'll be able to assess the problem statement and unpack and answer any problem the right way. This approach was created by FAANG’s hiring managers to help us prepare for the typical rounds of interviews at major tech companies like Apple, Google, Meta, Microsoft, and Amazon.

By the end of this module, we'll have the skills we need to unlock even the most challenging questions, grok the coding interview, and level up our career with confidence.

Coding Interview Patterns

# Statement
Given an array of integers, `nums`,  sorted in ascending order, your task is to construct a height-balanced binary search tree (BST) from this array.

In a height-balanced BST, the difference of heights of the left subtree and right subtree of any node is not more than 1.

> **Note:** There can be multiple valid BSTs for a given input.

**Constraints:**


* $1 \leq$ `nums.length` $\leq 10^3$
* $-10^4 \leq$ `nums[i]` $\leq 10^4$
* `nums` is sorted in strictly ascending order.
