Solution: Word Search II
Explore how to solve the Word Search II problem by combining trie data structure and backtracking. Learn to optimize search by constructing a trie from input words and using depth-first search to find words in a letter grid efficiently. Understand the algorithm's time and space complexity to handle multiple strings and improve search performance.

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
