Solution: Word Search II
Explore how to implement an efficient solution to Word Search II by combining trie data structures with backtracking in Go. This lesson teaches you to build a trie for prefix matching and apply depth-first search to find words in a 2D grid. Understand how this approach reduces time complexity compared to naive backtracking, and analyze the space complexity of the trie to optimize your solution.
We'll cover the following...
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
