DIY: Word Search II
Explore how to implement a word search algorithm that finds given strings in a 2D character grid using depth-first search and Trie optimization. Understand grid traversal rules and apply coding logic to identify words without diagonal neighbors. Develop the find_strings function to solve the challenge, improving skills for similar coding interview problems.

Problem statement
In this challenge, you will be given a list of strings that you need to find in the 2D grid. Neighboring characters can be combined to form strings. Remember that the diagonals are not included in neighboring characters; only up, down, right, and left neighbors can be considered. ...
