Solution: Word Search II
Explore how to efficiently solve the Word Search II problem by implementing a trie to represent prefixes of words and using backtracking with depth-first search over a 2D grid. Understand how this approach prunes the search space, improving time complexity, and learn to manage space complexity by building a trie for the given input list of words.

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
