Solution: Word Search II
Explore how to implement an efficient solution for Word Search II by combining backtracking with a Trie data structure. Understand how using a Trie reduces search space and improves time complexity when finding multiple words in a grid. This lesson helps you apply these techniques to handle string searches effectively in coding interviews.

Statement
You are given a list of strings that you need to find in a 2D grid of letters such that the string can be constructed from letters in sequentially adjacent cells. The cells are considered sequentially adjacent when they are neighbors to each other either horizontally or vertically. The solution should return a list containing the strings from the input list that were found in the grid.
Constraints:
- rows, columns
-
words.length
