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

Ace the JavaScript Coding Interview

This module teaches us the underlying patterns behind common coding interview questions. By learning these essential patterns, we'll be able to unpack and answer any problem the right way—just by assessing the problem statement. This approach was created by FAANG 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 strings called `products` and a word to search, design a system that, when each character of the searched word is typed, suggests at most three product names from `products`. Suggested products should share a common prefix with the searched word. If more than three products exist with a common prefix, return the three product names that appear first in lexicographical order.

Return the suggested products, which will be a list of lists after each character of searched word is typed.

**Constraints:**
* $1 \leq$ `products.length` $\leq 1000$
* $1 \leq$ `products[i].length` $\leq 3000$
* $1 \leq$ `sum(products[i].length)` $\leq 2 \times 10^3$
* All the strings of products are unique.
* `products[i]` consists of lowercase English letters.
* $1 \leq$ `searched word.length` $\leq 1000$
* The searched word consists of lowercase English letters.
