Solution: Word Search II
Explore how to solve the Word Search II problem efficiently by constructing a trie of words and using backtracking with depth-first search on a 2D grid. Understand how this approach reduces search space and improves performance compared to naive methods, while managing time and space complexity effectively.

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
